摘要
主要从比较的角度研究了适合典型工业过程的4种PID控制器参数的整定方法,包括临界比例度法、衰减曲线法、鲁棒PID参数整定法和ISTE最优参数整定法。数字仿真以一阶惯性加时滞过程为研究对象,并对一物理对象进行了实时控制实验。结果表明,这4种方法都具有很好的系统跟踪和抗干扰性能。但是在鲁棒性方面,鲁棒PID参数整定法和ISTE最优参数整定法明显优越于其他两种方法。
Four parameter-tuning methods of PID controllers,i, e. critical proportional method （Z-N method）, Damping oscillatory method, robust PID Parameter Tuning method and ISTE optimal Parameter Tuning method are studied comparatively. These methods can be applied in the typical industrial processes. A process with one order plus time delay is selected as the typical process and equipment is also chosen to carry out real-time experiment in laboratory. The results show that the four methods all have a good behavior in the system tracking and disturbance-rejection performance when there are no model errors. While the process model mismatches exist the robust PID tuning method and ISTE optimal tuning method have shown very good robustness comparing with the other two methods.
