| Abstract: | 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. |
