Time Domain and Frequency Domain Analysis of PID Parameter Tuning Method
The control performance of PID depends on its parameter tuning.There are many tuning methods for PID,and different tuning methods are used for different controlled objects,resulting in significant differences in control effectiveness.At present,there is a lack of guidance on the selection of PID parameter tuning methods in research.Therefore,through five examples,the characteristics of PID tuning methods are analyzed and compared from the time domain and frequency domain,providing reference for the selection of PID parameter tuning methods.The results show that if you want to obtain a fast response,can choose the Ziegler Nichols(ZN)tuning method,and if you want to obtain a mild response curve,can choose the NCC tuning method.
