There are many structures and types of mechatronics servo control systems, but from the perspective of automatic control theory, servo control systems generally include five parts: controller, controlled target, fulfillment, detection and comparison.
1. Comparison link
The comparison link is to compare the input command signal with the feedback signal of the system to obtain the error signal between the output and the input, which is generally realized by a special circuit or computer.
2. a controller
The manipulator is generally a computer or PID (proportional, integral, and derivative) control circuit, and its main task is to transform the error signal output by the comparison element to manipulate the performance element to act as required.
3. Fulfillment
The function of the performance link is to convert the input energy into mechanical energy according to the requirements of the control signal to drive the controlled target operation. The fulfillment elements in the mechatronics system generally refer to various motors or hydraulic, pneumatic servo mechanisms, etc.
4. Accused target
The target is an object to be manipulated, such as a robotic arm or a mechanical work platform.
5. Detection link
The detection link refers to the equipment that can measure the output and convert it into the dimensions required by the comparison link, which generally includes sensors and conversion circuits.
