具有未知时变参数系统的$\mathcal{L}_1$自适应控制器保证瞬态性能:I部分

Guaranteed Transient Performance with $\mathcal{L}_1$ Adaptive Controller for Systems with Unknown Time-varying Parameters: Part I

Chengyu Cao, Naira Hovakimyan

摘要:

针对具有时变未知参数和时变有界扰动的不确定性系统,提出了一种新的自适应控制方法。该自适应控制器能同时保证系统输入输出信号的一致有界暂态渐近跟踪。通过增加自适应增益,可以系统地提高性能界限。具有时变摩擦力的机械臂的仿真验证了理论研究结果。

英文摘要:

This paper presents a novel adaptive control methodology for uncertain systems with time-varying unknown parameters and time-varying bounded disturbance. The adaptive controller ensures uniformly bounded transient and asymptotic tracking for system's both signals, input and output, simultaneously. The performance bounds can be systematically improved by increasing the adaptation gain. Simulations of a robotic arm with time-varying friction verify the theoretical findings.
