Abstract :
Permanent magnet synchronous motor (PMSM) is a typical nonlinear multivariable coupled system. It is sensitive to the load disturbance and the changing of motor parameters such as stator inductance. Magnetic-field distribution is observed by finite element analysis, and inductance parametric variations are obtained. To improve dynamic quality of PMSM control system, a new exponent reaching law is proposed. The results demonstrate that the novel speed controller can improve dynamic response performance and robustness characteristics of PMSM drive.
