PI Controllers Tuning Method of Permanent Magnet Servo System Based on Optimal Open-Loop Cut-Off Frequency Learning
摘要
Abstract
This paper proposes a parameter tuning methodology for the PI controller of permanent magnet servo system based on the optimal open-loop cutoff frequency.The analytic expressions of the current loop and the speed loop PI controller parameters are derived for the double PI control system with the speed/current cascading of permanent magnet synchronous motor based on a motor frequency domain mathematical model in the synchronous rotating reference frame.According to the requirements of the desired system,the performance evaluation functions of the current loop and the speed loop are constructed respectively starting from the time domain analysis.And learning the optimal open-loop cut-off frequency by iterating the minimum evaluation function value under a given excitation signal,so as to implement the parameter tuning of the current loop and speed loop PI controller.Finally,the validity and feasibility of the proposed methodology are verified through the experimental results on the twin trawling servo platform.关键词
