Abstract: A novel indirect adaptive fuzzy control scheme is proposed for the concerted driving control of six-wheel lunar rover.Based on the Lyapunov theory,it is proven that the designed scheme not only makes the tracking errors converge to a small neighborhood of the origin,but also reduces the tracking errors through increasing the value of designed parameters,and the control accuracy is improved.Simulation results on the concerted driving control of lunar rover verify the efficiency of the approach proposed.

Key words: lunar rover, adaptive control, fuzzy control, accuracy, nonlinear system
