英文摘要：

An anti-windup adaptive sliding mode control method is proposed for the robust trajectory tracking problem of wheeled mobile robot with input saturation constraint. Taking into account the influence of uncertain factors such as system pa- rameters perturbation and external disturbances, a nonlinear extended state observer is designed to estimate the system uncertain factors. Then, based on the estimated value, an anti-windup adaptive sliding mode controller is presented to eliminate the influence of parameters perturbation, external disturbance and input saturation con- straint on the system control performance. Comparative simulation results are given to demonstrate the superior performance and effectiveness of the proposed control method.
