Flux-Weakening Drive for IPMSM Based on Model Predictive Control

This paper presents a flux-weakening model predictive control (FW-MPC) for the interior permanent magnet synchronous motor (IPMSM) drive system. The FW is strategy to extend IPMSM’s operating region. However, primary needs track torque reference and maximize electrical per current amplitude with voltage limitations. two objects make it impossible solve problem using optimization method. We proposed an equivalent simplify complex problem, including objective functions. MPC selected as controller due its high robustness transient performance. constraints from are added in IPMSM simulation experiment results indicate that FW-MPC feasible effective driving can find optimal point maximum satisfying Therefore, region, benefiting application.
