Adaptive backstepping control of wheeled inverted pendulums models

In this paper, the state feedback control of wheeled inverted pendulum (WIP) used for mobile transportation has been investigated. The dynamic unstable balance and nonholonomic constraints inherent degrade the performance when the WIP operates in path-following mode. Through a suitable coordinates transformation, the WIP model is formulated into a parametric strict feedback form. Then, backstepping-based adaptive control is designed to achieve output tracking for the WIP. Simulation results are provided to show the effectiveness of the control proposed.
