Servo control principle
The biggest feature of the servo system: the control mode through the feedback signal [can be done to compare the command value with the target value, thus greatly reducing the error situation].
What is a feedback signal: after giving instructions to the control object, correctly track and find out the current value, and feedback the deviation value of the control content at any time, after the target object reaches the destination, feedback the position value, and so on.
Control process: The position of the mechanical body is detected, and the loop is a closed system, which is called a fully closed loop. In contrast, the loop system that detects the end of the motor shaft is called a semi-closed loop.

Internal structure of servo drive
Rectifier part: Through the rectifier part, the AC power supply is changed into DC power supply, and the capacitor filter generates a smooth and non-pulsating DC power supply.
Inverter: The SPWM signal from the control department drives the IGBT and changes the DC power supply into SPWM waveform to drive the servo motor.
Control part: The servo unit adopts a fully digital structure, through high-performance hardware support, to achieve closed-loop control software, now all the servo has been adopted (DSP digital signal processing) chip, DSP, can perform the position, speed, torque and current controller functions. The PWM signal control signal acts on the power drive unit, and can receive the processing position and current feedback, and has a communication interface.
Encoder: The servo motor is equipped with a high-performance Angle measurement encoder that accurately measures the position of the rotor and the speed of the motor.
