We present preliminary results on exact stability of hierarchical high order sliding mode (HOSM) controlled systems with smooth perturbations. We solve the exact tracking control problem for triangular systems of second order hence, our results are a starting point for backstepping HOSM control. The approach is based on the so-called quasi-continuous high order sliding modes algorithm however, we...
Sliding mode control is a typical nonlinear control strategy which was easy realized and with strong robustness, in this paper, a neuro sliding mode controller was designed with RBF neural networks and the stability of the proposed control scheme is proved by Lyapnouv theorem. For the chattering of sliding mode control are often derive from switching gain, the gain was adjusted with neural networks...
This paper presents the design of a set of sliding mode controllers for a quadrotor vertical take-off and landing (VTOL) unmanned air vehicle. To facilitate the design process of this under-actuated system, this paper proposes the use of a simple yet effective method to plan the action of each variable controller in the system and hence enhance the performance of the quadrotor. To stabilize the overall...
This paper proposes an adaptive fast terminal sliding mode control for a class of multiple input nonlinear systems with time-varying mismatched uncertainties via LMI approach. First, a novel fast terminal sliding surface design method for a class of nonlinear systems is proposed based on Lyapunov method. The sufficient conditions are provided for the uncertain system on the sliding surface, such that...
