The components of the control system and the basic process of control are briefly described

1. Internal environment.

The internal environment is the internal control system that influences and restricts the enterprise.

A general term for the various internal factors established and implemented, which is the basis for the implementation of internal control. The internal environment mainly includes the governance structure, organizational structure and distribution of rights and responsibilities, and corporate culture.

Human Resources Policy, Internal Audit.

mechanism, anti-fraud mechanism, etc.

2. Risk assessment.

Risk assessment is to identify and scientifically analyze the impact on corporate strategy in a timely manner.

and business management objectives.

The process of realizing various uncertainties and adopting coping strategies is an important part and content of the implementation of internal control. Risk assessment mainly includes goal setting and risk identification.

Risk analysis and risk response.

3. Control measures.

Control measures are the methods and means taken to ensure the realization of the internal control objectives of the enterprise based on the results of risk assessment and combined with risk response strategies, and are the specific methods and carriers for the implementation of internal control. The control measures are formulated according to the characteristics and requirements of the specific business and matters of the enterprise, mainly including the control of division of responsibilities, authorization control, audit and approval control, budget control, property protection control, accounting system control, internal reporting control, economic activity analysis control, performance appraisal control, information technology control, etc.

4. Information and communication.

Information and communication is timely, accurate and complete collection and operation and management of enterprises.

The process of timely transmission, effective communication and correct application of this information between the relevant levels of the enterprise in an appropriate manner is an important condition for the implementation of internal control. Information and communication mainly include the information collection mechanism and the communication mechanism within the enterprise and with the relevant parties outside the enterprise.

5. Supervision and inspection.

Supervision and inspection is the process of supervising, inspecting and evaluating the soundness, rationality and effectiveness of the internal control system of an enterprise, forming a written report and dealing with it accordingly, which is an important guarantee for the implementation of internal control. Supervision and inspection mainly include continuous supervision and inspection of the overall situation of the establishment and implementation of the internal control system, special supervision and inspection of a certain aspect or some aspects of internal control, as well as the submission of corresponding inspection reports and the proposal of targeted improvement measures. The self-assessment of internal control is an important part of internal control supervision and inspection.

The recipient will send the information back to the sender for verification. According to the feedback information, the original information will be affirmed or corrected. Look at the recipient's or your own reaction.

3. Briefly describe the components of the control system and the basic process of control.

A: The elements of a control system include; The principle of focus, the principle of timeliness, the principle of flexibility. , the principle of economy.

Operability principle. The basic processes of control include; 1. Determine the control standards. 2. Measure the implementation according to the standard. 3. Correct deviations.

There are four elements that must be present for control to be effective: first, the control system must be measurable and controllable, and people can understand the standards accordingly; Clause.

Second, there is a way to measure this characteristic; Clause.

(iii) the use of known methods to compare actual and planned results and to evaluate the gap between them; Clause.

Fourth, there is a regulatory system to ensure that known standards are adjusted if necessary.

The basic process of control:

1. Determine the control standards.

Including time standards, cost standards, quantity standards, quality standards, behavior standards, etc. A good standard should meet: inclusiveness and consistency; Viability; Stability.

2. Measure the implementation according to the standard.

First of all, it is necessary to clarify the means and methods of measurement, set up monitoring institutions, and implement measurement and inspection personnel; Second, there is a lot of information to be gained by measuring the work.

3. Correct deviations.

There are a few things that must be done:

1) Determine the cause of the deviation, whether it is a work error or a poor plan.

2) To improve the efficiency of remediation, in addition to strengthening pre-control, on-site control should be mainly adopted.

3) Develop remedial measures and adopt appropriate remedial tools.

4) Take control measures to achieve the purpose of remediation. The measures include the adjustment and revision of the original plan; improving technology; Improve organizational work.

The steps of the above process constitute a complete control system, complete a cycle, through each cycle, so that the deviation is continuously reduced, to ensure that the goal is achieved.

The classification and characteristics are as follows:1. Operation guidance control system. Advantages: simple structure, flexible and safe control, disadvantage is that it is operated by human, the speed is limited, and multiple objects cannot be controlled.

2. Direct digital control system (DDC), good real-time, reliable, high auspiciousness and strong adaptability.

3. The supervision and control system (SSC) is always in the best working condition in the production process.

4. Parting control system (DCS), decentralized control, centralized operation, hierarchical management.

5. Fieldbus control system (FCS) can reduce costs and improve reliability, and can realize a truly open interconnection system structure.

Summary. A control system is a technology that converts an input signal into an output signal and is used to control and regulate various industrial, production, or automated processes. Its main function is to make the controlled object (such as machine, equipment, etc.) run according to the predetermined law, so as to achieve the control goal.

A control system is a technology that converts an input signal into an output signal and is used to control and regulate various industrial, production or automation processes. Its main function is to make the controlled object (such as machines, equipment, etc.) run according to the predetermined law, and achieve the control goal from the branch.

The control system has the following characteristics:1Feedback:

The control system can detect the output and compare it with the expected value through a feedback mechanism, and adjust the input to achieve better control from the previous time. 2.Automation:

The early production system can realize automatic control, reduce manual intervention and improve the efficiency of production.

3.Stability: The control system has stability, that is, it can still maintain a stable output result when the external environment changes.

4.Robustness: The control system is robust, that is, it can maintain normal operation in the face of interference or failure.

5.Reliability: The control system needs to have high reliability to ensure the stable operation of the pants for a long time. 6.Flexibility: Sakura systems need to be flexible and able to adapt to different mission needs and environmental conditions.

The control system is an important nuclear envy technology means, which is widely used in the fields of industry, production and automation. With feedback, Wyeth beam automation, stability, robustness, reliability, and flexibility, it can help companies improve productivity, reduce costs, and improve product quality and forward reliability.

1. The posture of the control object: the control object is also known as the controlled object. In the automatic control system, it generally refers to the controlled trouser preparation or process as the object, such as the control of reactor and distillation equipment, or the control of pure adiabatic process and combustion process of balance transfer.

From the perspective of quantitative analysis and design, the control object is only part of the factors that affect the input and output parameters of the controlled equipment or process, but not the whole of the equipment.

2. Control objectives: control objectives are the key to determining the operation mode and direction of internal control, and are also the starting point for understanding the basic theory of internal control;

3. Control subject: The control subject refers to the dominant position relative to the controlled party between things that have a control relationship.

Please provide a brief description of the components of the control system.

Correct answer: The control system is composed of a controlled object and a control device, in general, the control device consists of: a measuring element, a comparator element, an amplification element, an actuator, a calibration device, and a given element, in which the measuring element, the comparator element and the actuator are indispensable.

The basic requirements of automatic control system are stability, rapidity and accuracy. The system is in equilibrium before the disturbance, and the system deviates from the original equilibrium state after the disturbance, and if the system can return to the equilibrium state before the disturbance disappears, the system is said to be stable. The various process conditions in the production process cannot be static.

In particular, chemical production, most of which are continuous production, the equipment is related to each other, when one of the process conditions of one of the sources changes, the fiber can cause some parameters in other equipment to fluctuate more or less, deviating from the normal process conditions. Of course, self-regulation means that there is no need for direct human involvement. "

Any system is a collection of elements linked together by a chain of cause and effect. This relationship between elements is called coupling. Cybernetics is the study of the control and regulation of coupled operating systems.

In order to control the operation of the coupled system, the control criterion z of the system must be determined. The value of the control criterion z is a function of a parameter s that is constantly changing, i.e., z f(s).

The deviation between the output of the system and the standard value z can be corrected by adjusting the system, so that the control of the system can be realized.
