扩充响应曲线法的递推求解及其在温度自适应控制中的应用

Recursive Solution to Expanding Response Curve Method andIts Application to Temperature Control System

对扩充响应曲线法(ERCM)进行改进,提出的ERCM开环递推求解算法,简化了PID参数的整定过程.在PID零极点不变的基础上,将开环递推整定算法引入闭环系统中,实现了PID自适应控制.仿真与温度控制实验表明,改进的算法具有较好的鲁棒性和实用性。

To modify expanding response curve method（ERCM） for PID, an open-loop recursive solution to ERCM is proposed, which simplifies the parameter setting of PID. Based on the remaining of zeros and poles of PID, an adaptive PID control algorithm is achieved by applying the proposed recursive algorithm. Simulation and the temperature control experiment demonstrate the robustness and practicability of the proposed algorithm.
