摘要
针对永磁同步电机调速系统易受突变负载影响导致转速下降的问题,结合二阶自抗扰控制器,实现了电机自抗扰控制.首先,给出了电机d-q轴数学模型,解决了ABC坐标系下电机多变量、非线性等问题;其次,针对电机d-q轴下的数学模型研究了q轴二阶自抗扰控制器;最后,在MATLAB/Simulink中进行了变速和加负载仿真,结果表明,二阶自抗扰控制器具有较好的鲁棒性、抗扰性和动态响应性.
Abstract
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.
