| Abstract |
A pennanent magnet synchronous motors (PMSM) control scheme is proposed. The scheme is based on an optimality algorithm to minimize the magnitude of stator current. This algorithm is used to detenninate the optimal angle between the flux and the current vectors. The outputs of the optimality algorithm in rotor frame, are used to generate three reference values for the statoric currents that are feed to an hysteresis current controlled
inverter. Rotor position information needed to calculate the reference stator currents is obtained by a position estimation algorithm, based on flux determination by voltage integration.
Computer simulation shows that the proposed scheme accurately controls the PMSM. |
