In this paper, we present a new method for designing higher order sliding mode controller (HOSMC) with adaptive switching gain by defining a new PI sliding surface and employing a linear state feedback. The objective is to force the outputs of a nonlinear SISO system and their derivatives up to a certain order, track the states of a linear system with desired properties. The main property of proposed controller is that it does not need an upper bound for the uncertainty and moreover, the switching gain increases and decreases according to the system circumstances by employing an adaptation procedure. Then, chattering is removed completely by using the HOSMC with a small switching gain. Finally, we have used the proposed method to control and synchronize of chaotic uncertain systems.
