| Abstract: | On the base of finite element solution for magnetic field and torque calculations, a variable structure control(VSC) of a switched reluctance motor(SRM) drive is presented according to the features of an SRM. After the switching function and the VSC system scheme of the SRM are given to execute the current and speed limitations, the effectiveness of VSC of an SRM drive is researched, and compared with that of a conventional PI regulator control. The simulation result shows that the VSC reduces obviously torque and speed ripples, improves lower speed performance in the SRM drive. The distinct improvement on insensitivity in parameter variations and disturbances, and on compensating for the nonlinear torque characteristics, is made in the meantime. |
