| 摘 要： | 本文在辩识过程模型参数的基础上,利用计算机求出对象的开环响应曲线,然后根据响应曲线法整定PI或PID参数的经验公式求出PI或PID参数。为了获得更好的控制效果,对所获得的PID参数进行了逐步地优化。该算法与其它自校正PID控制算法相比,具有适用范围更广的特点。计算机仿真和实时控制实验证实了该算法的有效性。

| Abstract: | In this paper,the open loop response curve is computed by a computer after the process paramter estimatio The parameters of PI or PID controller are computed by the method of respose curve. Then in order to obtain better control performance, the parameters of PI or PID controller are gradually optimized.This algorithm is with wider application range compared with the other self-tuning PID control algorithms. The computer simulation and real-time control trials shows a good result. |
