Wind energy conversion systems nonlinear tracking using finite-horizon SDRE

This research is devoted in the implementation of control system for a nonlinear Wind Energy Conversion Systems (WECS) with Permanent Magnet Synchronous Generators (PMSG). In which a finite-horizon nonlinear control technique based on State Dependent Riccati Equation (SDRE) for the design of a closed-loop, optimal controller is used. The idea of the proposed technique is the change of variables that converts the nonlinear differential Riccati equation to a linear Lyapunov differential equation. The proposed technique is effective for a wide range of operating points. Simulation results are given to illustrate the effectiveness of the proposed technique.
