In this paper, the nonlinear sliding mode control (SMC) with mismatch disturbances is proposed. We treat the problem of control with this class of disturbances and the chattering phenomena. The proposed method attenuates the effect of both uncertainties, external disturbances and eliminates the chattering phenomenon introduced by classical sliding mode(More)
In this paper, a new second order sliding mode control (SOSMC) for coupled (multi-input multi-output) MIMO nonlinear system is presented , the proposed method can be applied to a large class of nonlinear coupled MIMO processes affected by parameters uncertainties and disturbances. This algorithm are implemented on the three tanks test-bed system and the(More)
This paper is devoted to the study of the performances of a robust speed sensorless nonlinear control of permanent magnet synchronous machine. In the first part, the controllers are designed using two methods: the first one using the input output feedback linearization control and the second is a nonlinear control based on Lyapunov theory combined with(More)
The performance of a 1.5 MVA wind-power Doubly Fed Induction Generator (DFIG) under network fault is studied using simulator developed in MATLAB-SIMULINK. This paper investigates a new control method able to improve the fault-ride through capability of DFIG. In such generators the appearance of severe voltage sags at the coupling point make highlight(More)
