We propose a synchronization approach to solve a problem where multiple unicycle agents are required to follow individual reference trajectories while maintaining a time-varying formation. Motions of the agents are synchronized thanks to coupling terms in their feedback control laws. Under saturation constraints on the control signals, our control laws guarantee global asymptotic zeroing of the synchronization...
In this paper, an improved sliding mode algorithm with global asymptotic stability is presented for tracking control of nonholonomic mobile robot. Centroid offset parameters are used in the design of the controller, which can drive the position error to zero quickly in the premise of guaranteeing stability of the whole system. The Kinematics mathematical model and the position and posture error model...
This paper presents the problem of trajectory tracking control for the nonholonomic six-wheeled mobile robot. Based on backstepping control algorithm, a switch function for quasi-sliding mode control is designed and a quasi-sliding mode controller with global asymptotically stability is proposed for the kinematic model. This method simplifies the controller design and is applicable to the trajectory...
