Receding horizon tracking control of wheeled mobile robots

Abstract

In this paper, a receding horizon (RH) controller is developed for tracking control of a nonholonomic mobile robot. The control stability is guaranteed by adding a terminal-state penalty to the cost function and constraining the terminal state to a terminal-state region. The stability analysis in the terminal-state region is investigated, and a virtual controller is found. The analysis results show that the RH tracking control has simultaneous tracking and regulation capability. Simulation results are provided to verify the proposed control strategy. It is shown that the control strategy is feasible.
