On the basis of the given system of permanent magnet synchronous motor(PMSM) direct torque control(DTC)
a speed controller for making PMSM-DTC system suitable for higher requirements applications is designed.This paper proposes a new piecewise GPC algorithm which is integrated with stair-like generalized predictive control algorithm;the objective function is added to a weight for square of predictive and given values’ difference
and assigns different values to the weight in different periods.The...
