Abstract: In this paper, we propose a new adaptive sliding mode control for nonlinear systems which are affine with respect to control and where the free term of state representation is assumed to be unknown and modelled using Volterra series. The proposed control law depends on the estimated parameters of Volterra series. The Lyapunov function was defined based on the sliding surface and the errors between the Volterra model parameters and their estimated values. The Lyapunov function is defined as positive and decreasing which shows the systems studied. An example of simulation and a validation on a real system are performed at the end of this paper to show the effectiveness of this approach.
Keywords: sliding mode; nonlinear; Lyapunov function; Volterra series.
