controller
The controller is the core component of a closed-loop servo control system, responsible for receiving input signals, processing error signals, and generating control signals. Controllers usually use microprocessors or digital signal processors, which have powerful computing power and rich control algorithms.
Actuator
The actuator is the executing component of a closed-loop servo control system, responsible for converting control signals into mechanical motion. The actuator usually uses servo motors, which have the characteristics of high precision, high response speed, and high stability.
sensor
Sensors are the detection components of closed-loop servo control systems, responsible for real-time detection of the system’s output signals and feedback of the detected signals to the controller. Sensors usually use encoders, photoelectric sensors, force sensors, etc., which have the characteristics of high precision and high stability.
Feedback loop
Feedback loop is an important component of closed-loop servo control system, responsible for feeding back the signals detected by sensors to the controller, forming closed-loop control. The design of feedback loop has a significant impact on the stability and accuracy of the system.
