摘要
建立了永磁同步电动机的仿射非线性数学模型,采用微分几何精确线性化理论,实现了对永磁同步电动机的精确线性化解耦,并给出了反馈控制算法,最后应用非线性变结构控制理论指数趋近律法进行设计,实现了一种较新的对永磁同步电动机的控制。仿真结果表明,该控制系统具有良好的动静态性能。
The nonlinear model of the PMSM was built. The nonlinear system of the motor was linearized by differential geometry transmission. The nonlinear system was turned to a new linear system. Finally a controller of the system is designed according to the method of the exponentially approaching rule of variable structure theory. To verify the effectiveness of the control scheme, some simulations were carried out and the results show satisfactory static and dynamic performances of the motor.
