description The paper presents a study for determination the optimal control law for a small horizontal axis windgenerator. Experimentally, using a mixed physical-analog laboratory model, were determined the state variables, corresponding to different wind speed values, for the optimum regimes of the wind turbine, based on the turbine theoretical estimated mathematical model. From a large multitude of possible optimum control laws, the relation between the current and the voltage of the DC-DC converter was considered for control law. This relation - control law, was expressed by a regression function, using the experimental obtained DC-DC converter (HDC from Fig.1) current-voltage pairs V HDC , I HDC . The obtained control law was implemented and verified on Matlab/Simulink model considering different wind speed variations. The simulation results confirm the opportunity end the quality of the adopted optimal control law.
