Stability Analysis of the Variable Speed Wind Turbine Using Sliding Mode Control

The sliding mode control is one among the best techniques for analysing the dynamics as well as maintaining the stability of a system. The problem of lack of stability and robustness in a variable speed wind turbine can be resolved by using this sliding mode control technique. The desired sliding mode dynamics can be attained by a suitable design of the switching function and on the switching surface, the sliding occurs; following the system achieving its desired system dynamics. This paper presents the sliding mode control scheme to improve the overall stability of the variable speed wind turbine system. The proposed strategy is applied and the results are obtained using MATLAB. The results obtained demonstrate its effectiveness in improving the overall system stability.
