Improved MPC for PMSM drives to reduce switching losses

This paper presents an improved model predictive control (MPC) for permanent magnet synchronous motor (PMSM) fed by a voltage source inverter (VSI), in order to reduce switching losses. The MPC strategy is based on a cost function generally established for performance purposes and leads to switching states to be applied for VSI control. In this work, the cost function is improved in order to reduce changing states so to reduce switching losses. Simulations are carried out to illustrate the theoretical development and results demonstrate the effectiveness of the proposed approach.
