Design and implementation of adaptive dynamic controllers for wheeled mobile robots

This paper presents a hybrid intelligent algorithm for path planning and trajectory-tracking control of a wheeled mobile robot (WMR). By using the proposed controller, the WMR can successfully finish the object of trajectory-tracking. First of all, we use D* Lite algorithm to determine the shortest path between the initial position and the destination position for the WMR. Then by using the proposed controller, the WMR can move along the path and arrive at the destination successfully. The controller is divided in two parts, which are kinematic controller and dynamic controller. The asymptotic stability of both kinematic and dynamic controllers is proven by Lyapunov theory. Finally, experiments show that this method can achieve good results.
