Robust Control Design of Uncertain Strict Feedback Systems Using Adaptive Filters

摘要

This paper concerns on the tracking problem of uncertain strict feedback systems. By employing the adaptive filters, a robust state feedback control scheme is derived, where a common compensator is utilized to eliminate the effects induced by each filters. Compared with the existing results using standard dynamic surface control approach, the closed loop stability does not depend on small filter time constants. Finally, the correctness of the developed methodology is demonstrated via a numerical example.
