Tracking Control Design for a Class of Mobile Robot with a Single Trailer via Differential Flatness Approach
In this paper, a nonlinear disturbance observer (NDO) is designed for mobile robot with a single trailer. To realize the tracking control objective, the considered mobile robot is transformed into chained-form system by differential flatness approach. The global asymptotic stability of the presented disturbance observer is guaranteed by appropriately choosing design function. Under this NDO, a tracking controller is proposed to force the system trajectory track the desired trajectory.
