This paper describes linear quadratic regulation(LQR) application for pitch control of a Horizontal tidal current turbine power generator. Using simplified dynamic model of the turbine, we can obtain nonlinear dynamic equation of the turbine. For designing controller, state-space model is obtained at operating point using taylor series and then an LQR controller is designed. Then Using the obtained turbine model, the LQR controller is simulated using Matlab simulink to investigate the responses of the pitch angle and the rotational speed of the generator.
