摘要: 提出了一种基于递推参数估计的PID参数频域整定方法，仅利用受控过程的一般输入/输出信息及整定后的闭环品质判断，经过一至两次整定，即可得到有效的PID参数，仿真结果表明了其良好的控制品质．Abstract: This paper gives a PID autotuning method in frequency domain based on recursive estimation.Based on the data of the general input/output of the process and the judgement of the closeloop characteristic after tuning,the effective parameters of the PID controller can be get in one or two times of retuning.The simulation proved the good characters of the method.
