Dynamic Model-based Adaptive Sliding-mode Trajectory Tracking Control over Wheeled Mobile Robot
摘要
Abstract
In order to control a wheeled mobile robot whose mass center does not coincide with its geometrical center,we propose an adaptive sliding-mode trajectory tracking control law that has global asymptotical stability.We design a kinematic controller according to the kinematic model of the wheeled mobile robot.Using the kinematic model and the kinematic controller,we design an adaptive sliding-mode controller with the backstepping technique and the integral sliding-mode control algorithm,which can overcome unknown disturbances effectively.We use the Lyapunov stability theory to prove the stability of the wheeled mobile robot and its tracking error convergence.Our control law satisfies the trajectory tracking requirements for the wheeled mobile robot and has good robustness.Finally,we use two simulation examples to demonstrate the effectiveness and correctness of our control law.关键词
