| 英文摘要 |
| In this article, we investigate the adaptive output feedback stabilizing control problem for a class of uncertain
cascaded chained-form nonholonomic systems with unmodeled dynamics and unknown parameters. Using only the output
information, we propose a novel adaptive output feedback stabilizing control scheme with the help of a dynamic gain observer and the adaptive estimator. The backstepping recursive method plays a key role in this procedure. Additionally, a
switching adaptive control strategy is developed to get around the continuous stabilization burden associated with nonholonomic systems. The proposed control scheme guarantees the system states in closed-loop system converge to the origin.
The simulation results illustrate the efficacy of the presented algorithm. |
