摘要

针对执行机构失效未知的参数严格反馈非线性系统，基于两种驱动模型的匹配设计，提出了两种直接自适应控制方案。采用反步设计技术，提出了自适应状态反馈控制律，在存在未知执行器故障和未知参数的情况下，实现了输出的渐近跟踪，保证了闭环信号的有界性。

Adaptive control of parametric-strict-feedback nonlinear systems with actuator failures

Two direct adaptive control schemes are developed for parametric-strict-feedback nonlinear systems with unknown actuator failures, based on matching designs for two actuation models. Using a backstepping design technique, adaptive state feedback control laws are proposed to achieve asymptotic output tracking and ensure closed-loop signal boundedness, despite the presence of unknown actuator failures and unknown parameters.
