Abstract

In this paper a discrete tracking control algorithm for a non-holonomic two–wheeled mobile robot (WMR) is presented. The basis of the control algorithm is an Adaptive Critic Design (ACD) in two model-based configurations: Heuristic Dynamic Programming (HDP) and Dual Heuristic Programming (DHP). In proposed control algorithm Actor–Critic structure, composed of two neural networks (NN), is supplied by a PD controller and a supervisory term derived from the Lyapunov stability theorem. The control algorithm works on-line and does not require preliminary learning. Verification of the proposed control algorithm was realized on a WMR Pioneer–2DX.
