PI控制器分离参数整定方法及装置
By using the response curve method and the phase margin method to tune the PI controller parameters, the problems of traditional PI controllers being time-consuming and struggling to balance stability, speed, and accuracy under complex controlled objects are solved. This achieves more flexible parameter tuning and reduces overshoot and settling time.

AI Technical Summary
Traditional PI controller parameter tuning methods are time-consuming under complex controlled objects and struggle to balance system stability, speed, and accuracy, often resulting in large overshoot and long settling times.
The parameters of the controlled object are identified by the response curve method, and the parameters of the PI controller are tuned based on the phase margin method. The PI controller parameters are only related to the steady-state gain of the controlled object, decoupled from the time scale, and are suitable for pure delay elements, high-order inertial elements, and first-order inertial elements with hysteresis.
It provides a more flexible and convenient way to tune parameters, improves system stability, speed and accuracy, and reduces overshoot and settling time.
