Composite control for disturbed direct-driven surface-mounted permanent magnet synchronous generator with model prediction strategy

In order to obtain the best power in wind energy conversion system (WECS) of direct-driven surface-mounted permanent magnet synchronous generator (SPMSG), active disturbance rejection control (ADRC) is introduced track motor speed real time. The algorithm provides a new design concept and an inherent robust controller component that requires very little information. Aiming at problem parameter mutation caused by internal factors external environment changes, adaptive with multi identification designed, changes compensated model predictive current (MPC) technology for sudden change designed accelerate response loop, so as weaken estimation controller, make more accurate. Simulation results show proposed strategy effective satisfactory.
