Wheeled mobile robots are widely used in intelligent logistics, unmanned delivery, industrial inspection, service robots, and other fields due to their simple structure, flexible mobility, and low energy consumption. However, during actual operation, robots often encounter complex operating conditions such as tire slip, model uncertainty, input saturation, and external disturbances, which can lead to reduced trajectory tracking accuracy or even system instability. In recent years, scholars in China and abroad have proposed numerous advanced control methods for the control problems of wheeled robots under different operating conditions, including sliding mode control, disturbance observer-bas...
