At same time, track coordinate detected Failing recognize finally passes estimated...

We present a control strategy for nonlinear nontriangular uncertain systems. The proposed method is synergy between the dynamic adaptive backstepping (DAB) and integral sliding mode (ISM) referred to as DAB-ISMC. Our main objective find recursive procedure transform system into an implementable form that enables designing law which almost eliminates reaching-phase. further facilitates minimization of chattering believed be shortcoming control.

In addition, eradicate influence norm bounded second step. Finally, an algorithm on regulate trajectories origin. To validate effectiveness proposed scheme numerical example provided.

This paper shows the effectiveness of disturbance observer (DO) based sliding mode control (SMC) scheme as compared to traditional SMC. Both methods are simulated for variable speed wind turbine (VSWT) ensure asymptotic tracking rotor even in presence disturbances. Two mass model VSWT is derived which includes damping effect rotor's blade and generator. The stiffness low-speed shaft also taken into account while modelling system. dynamic contains both matched mismatched uncertainties....
