Fast torque control system of PMSM based on model predictive control

This paper describes a fast torque control system of permanent magnet synchronous motor (PMSM) based on model predictive control (MPC). This torque controller selects directly one of the voltage vector of voltage source PWM inverter considering voltage saturation explicitly. To obtain the fast torque response at the transient state and the stable current response at the steady state, the problem with selecting the voltage vector to output is formulated based on MPC. In this paper, real-time implementation method using a look-up table, which is designed beforehand, is discussed and the experimental results are shown.
