Cascade Model Predictive Current Control for Five-Phase Permanent Magnet Synchronous Motor

As to the model predictive control for five-phase permanent magnet synchronous motor (PMSM), it is difficult ensure optimal performance by using calculation method obtain weighting factor. To solve this problem, a cascade current based on idea of sequential proposed PMSM first time. Firstly, principle selecting voltage vector analyzed in detail. Then, combined with characteristics PMSM, priority controlled variables set designing two cost function schemes without weight The maximum torque scheme can generate trapezoidal stator voltage, improving DC bus utilization rate and system loading capacity. minimum harmonic reduce current, obtaining small noise vibration. experimental results indicate that optimality applied. Therefore, obtains good under different working operation, such as ripple, fast dynamic response, current.
