RBFNN Siding Mode Control Based on Semi-Physical Simulation Platform

Abstract

Based on MATLAB RTW semi-physical simulation platform, a siding mode control algorithm is presented for a kind of uncertain time-delay system. Through a particular linear transformation, the original uncertain time-delay system was first transformed into a delay-free system. Based on the transformed system, a design method of optimal sliding mode with a quadratic performance index minimized was proposed. An appropriate control law which is approached by a RBFN and the weight of the network is tuned on line using adaptive algorithm to force the system states to reach the sliding manifold in finite time. Simulation results show the efficiency and superiority of the proposed method.
