This paper deals with the estimation of the power coefficient in a wind turbine connected to a separately excited dc generator with the aim of facilitating maximum power point tracking control design. More precisely, we bring an improvement on the observer design given in a previous work by including a possible dynamical model of the power coefficient. It is shown that the proposed observer have a better response compared to the previous observer. Additionally, it is shown that the observer is capable of handing measurement noise and that it can be easily extended to other WECS where different types of generators are employed.
