Finite-Set Predictive Control with Disturbance Rejection Capability for PMSGs in Wind Turbine Applications

A finite-set predictive control (FSPC) approach is designed by considering the discrete-time model of the system under control. Therefore, variations of the model parameters and disturbances due to un-modeled dynamics deteriorate the performance of the FSPC. In order to overcome this problem, this paper proposes a FSPC strategy with an equivalent input disturbance (EID) observer for permanent-magnet synchronous generators (PMSGs) in wind turbine applications. The proposed EID observer estimates the total disturbance due to variations of the model parameters and un-modeled dynamics and considers it in the design of the controller. Experimental results are given to validate the performance of the proposed FSPC scheme.     «
