The predictive control of PMSM based on state space

In this paper, a multi-variable predictive controller of PMSM is discussed. A linearization state equation is setup by introducing the conception of expanded input. Based on the state equation, the multi-step predictive output of the system is educed, and the multi-variable predictive control law is achieved by minimizing the given performance function. And then the reference state of the system is designed; it insures the trajectory run to the proper state. The simulation results prove the controller is validity and stabilization.
