ENGLISHServo control system structure composition
2021-08-12
Servo system is mechatronics system, should be designed by mechatronics method. Servo system design, there is no fixed answer, there is no uniform method to get the answer. Different requirements of the servo system, can use different methods to design, so the structure of the servo system is different. Even if the same requirements of the servo system, different designers may also use different design methods, so get different design schemes.
The complexity of servo system structure determines the complexity of its design process. The design of the actual servo system is difficult to be successful once, and it often needs to be modified and debugged for many times to obtain satisfactory results. The following is only a brief introduction to the general steps and methods of servo system design.
Servo system structure composition
From the perspective of automatic control theory, the servo control system generally includes five parts: controller, controlled object, execution link, detection link and comparison link.
1. Comparison
The comparison link is to compare the input instruction signal with the feedback signal of the system, in order to obtain the deviation signal between the output and the input link, usually by the special circuit or computer to achieve.
2. Controller
Do you understand the structure, steps and methods of servo control system?
The controller is usually a computer or PID control circuit, its main task is to compare the component output deviation signal transformation processing, in order to control the implementation of the component according to the required action.
3. Implementation
The function of the execution link is to convert the input energy into mechanical energy according to the requirements of the control signal and drive the controlled object to work. Electromechanical integration system of the executive components generally refers to a variety of motor or electric cylinder, hydraulic, pneumatic servo mechanism, etc.
4. Controlled object
5. Detection
The detection link refers to the device that can measure the output and convert it into the dimensions required by the comparison link, generally including sensors and conversion circuits.
