Robustness improvement by using linear quadratic regulator control for PMSG
In order to improve the robustness of the control for Permanent Magnet Synchronous Generator (PMSG), the optimal linear quadratic regulator technique is adopted to both current and voltage controllers in this paper. Furthermore, an integral action is added to cancel the steady-state error. Control principles are analyzed and controller design is given in details. Simulation results reveal that the current can track perfectly the reference even in presence of disturbances, and the integral action did its job.
