The core of PID control is the adjustment of three parameters: proportional, integral and differentiated. By reasonably adjusting these three parameters, stable, fast and accurate control of the system can be achieved.
Positioning accuracy refers to the accuracy of the system to accurately reach the target position, speed accuracy refers to the error between the speed and expected speed of the system during motion, and acceleration accuracy refers to the error between the acceleration and expected acceleration of the system during motion.
The pros and cons of these indicators directly affect the performance and effect of the motion control system.
