Optimal tracking control of two-wheeled mobile robots based on model predictive control

Abstract

This paper presents an optimal tracking control using model predictive control for a two-wheeled mobile robot with a nonholonomic constraint. In the proposed method, the optimized control strategy can be obtained while satisfying some constraints imposed on input and state. The dynamics is modeled as a hybrid dynamical system so that the model predictive control can be applied to it. Some simulation and experimental results illustrate the effectiveness of the proposed method.
