This paper proposes a control strategy for an IPM synchronous generator-based variable speed wind turbine this control technique is simple and has many advantages over indirect vector control technique as in this scheme, the requirement of the continuous rotor position is eliminated as all the calculations are done in the stator reference frame and can eliminate some of the drawbacks of traditional indirect vector control scheme. This scheme possesses advantages such as lesser parameter dependence and reduced number of controllers compared with the traditional indirect vector control scheme Furthermore, the system is unaffected to variation in parameters because stator resistance is the only required criteria. This control technique is implemented in MATLAB/Sim power systems and the simulation results shows that this suggested control technique works well and can operate under constant and varying wind speeds. Finally, a sensorless speed estimator is implemented, which enables the wind turbine to operate without the mechanical speed sensor
