基于M序列相关辨识的温度自整定控制

提出了在控制回路中加入微幅多频二进制信号(M序列),利用在线相关辨识确定系统脉冲响应,再应用优化算法对PID的参数进行在线整定的控制方案.该方案被用于温度控制案例的试验结果表明是有效的.;By adding low-magnitude M sequence to the control system, online correlated identification method is used to determine system impulse response. Then, Optimal Algorithm is used to tune PID parameters online. Experiment which uses this method shows good control result
