Abstract

Abstract: Predictive control strategy is applied to permanent magnet synchronous motor control system, it can achieve fast dynamic response and high-precision tracking control, but depending on the mathematical model of the motor, the load disturbance will affect the control performance of system. A new control method combining an observer based on internal model control (IMC) and predictive control was presented. The inner-loop current controller and the outer-loop speed controller based separately on model predictive control algorithm and deadbeat current predictive control algorithm were designed to form dual-loop predictive control system. An IMC observer is designed to estimate the load disturbance, and torque-current compensation is produced as feedforward of speed loop to attenuate the disturbance. The simulation results show that the proposed method can improve the dynamic response performance and steady-state precision of the control system, and the robustness is greatly enhanced.
