Three-Loop Genetic Control of Permanent Magnet Synchronous Motor Based on Spindle PID Parameter Tuning
In order to further improve the genetic control accuracy of the three loops(position,speed and current)of the permanent magnet synchronous motor,a genetic algorithm is chosen to adjust the spindle parameters.The three-loop genetic control process of permanent magnet synchronous motor is established,and the parameters are rectified according to fuzzy PID.On the basis of identifying the parameters to the variable gain PI control,the convergence speed is achieved by setting the inertia weight coefficients.Feed tests are carried out in terms of linear signals,which promotes a significant improvement in the following performance.The results of the study show that relative to the artificial empirical method,the absolute error extremes and absolute error integrals of the three-loop genetic control method are reduced by about 30％,and a better following performance is achieved for the following error,which improves the following performance.This study helps to improve the control accuracy of permanent magnet synchronous motor and can also be broadened to other types of motor control fields.
