Abstract - This paper studies the problem of maximizing the take off power from a buoy type point absorber of a Wave Energy Converter. The paper offers a solution framework for the above mentioned problem under the linear quadratic Gaussian (LQG) control approach. The standard Kalman estimator technique is used to estimate the position and the velocity of the two body wave energy system. The optimal PTO force is computed and hence the maximum output power is achieved. A comparison with conventional approach reflects the superiority of this framework even under different values of mooring constant.
