Anonymous users2024-02-07Cybernetics is the study of the general laws of control and communication within animals (including humans) and machines, with an emphasis on mathematical relationships in the study process. It is an interdisciplinary discipline that integrates the control, information exchange, and feedback regulation of various systems, and spans many disciplines such as human engineering, control engineering, communication engineering, computer engineering, general physiology, neurophysiology, psychology, mathematics, logic, and sociology.
Basic Parts:1Information theory.
Information theory is mainly a statistical theory about the processing, transmission and storage of information in various pathways, including machines and biological organisms.
2.Theory of automatic control systems.
The theory of automatic control systems is mainly feedback theory, which includes the study of the general laws of regulation and control in machines and objects (nervous system, endocrine and other systems) from a functional point of view.
3.Automatic Fast Computer Theory.
The theory of automatic fast computers is the theory of automatic organizational logical processes that are similar to human thought processes.

Anonymous users2024-02-051. The basic concept of cybernetics is information and feedback. The process of receiving and using information is the process by which we regulate the contingencies of the external environment and live effectively in that environment. The commands we use to control the environment are all the information we give to the environment.
The reason why any organization is able to maintain its stability is because it has the means to obtain, use, maintain, and transmit information. Therefore, information and control are inseparable, and information theory is the basis of cybernetics. The process of information transformation can be simplified to the process of "information input, storage, processing, output and information", and there is "feedback" information here.
The so-called "feedback" is the process of transmitting back the results (real information) produced by the information (also known as given information) of the control system acting on the controlled system (object) and affecting the re-output of information. Wiener called anti-Russian a method of controlling the activities of the system, a process of transmitting and returning information, characterized by the adjustment of future behavior in accordance with past operations.
2. It is not difficult to see that the feedback mentioned in cybernetics is mainly the information feedback referred to from the perspective of information.
3. Feedback can be divided into two categories, namely positive feedback and negative feedback. If the feedback signal is to enhance the input effect of the system, that is, the difference between the given information and the real information of the control system tends to exacerbate the ongoing off-target activities of the system, then it tends to an unstable state or even a destabilizing state, which is called positive feedback. Conversely, if the feedback signal weakens the system input effect, i.e., the difference between the given information and the real information of the control system tends to resist the movement of the system that is deviating from the target, then it makes the system tend to a steady state, which is negative feedback.
4. Positive feedback makes the output of the system larger and larger, which can often be used to improve the sensitivity of the system; Negative feedback, on the other hand, can compensate for the effects of changes in certain factors within the system, so that the stability of the system increases.
Engineering Cybernetics is a systematic, comprehensive and in-depth exposition of the basic concepts, basic principles, basic methods and basic technologies of engineering cybernetics during Qian Xuesen's teaching at the California Institute of Technology and the Massachusetts Institute of Technology in the 50s of the 20th century, on the basis of summarizing the practical experience of science and engineering technology, laying a solid foundation for the new discipline of engineering cybernetics. >>>More

to control the device. The magnetron usually operates in mode, and the phase of the microwave electric field at the cavities of the two adjacent resonators is exactly 180°, that is, the microwave electric field is exactly opposite (Figure 2). Although this microwave field is a standing wave field, in the case of modulus, it is equivalent to two identical microwave fields moving in opposite directions on the circumference, and the phase velocity values of the two fields are equal. >>>More
