英文摘要：

Two-wheeled mobile robot is a typical nonholonomic underactuated system. Aiming at the path tracking and posture balance control problem of this kind of mobile robot, a control algorithm is proposed which integrates the kinematic controller designed by backstepping and the sliding mode dy- namics controller. The kinematic controller designed by backstepping is used to solve the control problem between velocity and position. Considering the uncertainties of the system and external dis- turbance, the sliding mode controller that has the characteristics of stability and robustness is used as the dynamics controller to realize the robot＇s speed and posture balance. The simulation results show that the method effectively realizes the two-wheeled mobile robot trajectory tracking in a stable and balanced mode.
