This paper is aimed at designing a nonlinear robust control techniques for two mass model
of variable speed wind turbine (VSWT) with better performance parameters and capability of
rejection of disturbances. Sliding Mode Control (SMC) is the most widely used robust
controller. The control scheme based on SMC ensures that system state (rotor speed) of
VSWT will converge to a desired speed in finite time. However, in conventional SMC the
system is robust against matched uncertainties only. Therefore an integral SMC is presented …

This paper is aimed at designing a nonlinear robust control techniques for two mass model of variable speed wind turbine (VSWT) with better performance parameters and capability of rejection of disturbances. Sliding Mode Control (SMC) is the most widely used robust controller. The control scheme based on SMC ensures that system state (rotor speed) of VSWT will converge to a desired speed in finite time. However, in conventional SMC the system is robust against matched uncertainties only. Therefore an integral SMC is presented that eliminate the effect of both match and mismatch uncertainties. Integral SMC (ISMC) is presented to track the speed of rotor of VSWT with an improved performance of the system at the cost of eliminating the effect of mismatch uncertainties.
