| Abstract: | Aiming at the complex problem of weight factor design of traditional model predictive control（MPC）, a multiobjective optimization model predictive control strategy without weighting factor was proposed by using the idea of hierarchical control. Taking advantage of the direct control of AC variable by MPC control algorithm, the reference equation and prediction equation of rotor current, stator current and stator power were derived inthetwo phase stationary coordinate system. Finally, a comparative simulation experiment was designed under the traditional multi-objective MPC control strategy and the weightless factor multi-objective MPC control strategy. The simulation results show that compared with the traditional multi-objective control strategy, the proposed control strategy has faster dynamic response speed, and improves the steady-state performance of the system. |
