Vector Control of Permanent Magnet Synchronous Motor Based on Second-order Active Disturbance Rejection
In order to solve the problem that the speed of permanent magnet synchronous motor speed control system is reduced due to sudden load,a second-order active disturbance rejection controller is combined to realize the motor active disturbance rejection control.Firstly,the d-q axis mathematical model of the motor is given,and the problems of multi-variable and nonlinear of the motor in ABC coordinate system are solved.Secondly,the q-axis second-order active disturbance rejection controller is researched according to the mathematical model of d-q axis.Finally,variable speed and load simulation are carried out in MATLAB/Simulink.The results show that the second-order ADRC has good robustness,immunity and dynamic response performance.
