Discrete super twisting control algorithm for the nonholonomic mobile robots tracking problem

The tracking control of nonholonomic mobile robots has been an important class of control problems. This paper deals with the design and real-time implementation of a discrete-time super twisting control algorithm for nonholonomic wheeled mobile robots, without the previous knowledged of the plant model or its parameters. In order to show the effectiveness of the proposed controller experimental results are included for a nonholonomic mobile robot QBot®3.
