AI总结:

本文分析了改进的L1自适应控制律,比较了其与原始控制律的性能,指出在允许轻微性能下降的情况下,无需零极点抵消技术即可用L1自适应控制律控制非最小相位系统。

摘要:

本文提出了对改进的L1自适应控制律的分析。该控制律的性能与原始控制律进行了比较。改进的L1控制律使用闭环系统动力学传递函数的直流增益。控制器性能略有下降。此外,此分析表明,在允许轻微性能下降的情况下,L1自适应控制律可用于控制非最小相位系统,而无需使用零极点抵消技术。L1自适应控制在应用前需要五个假设。由于对自适应控制律的修改,匹配的传输零点稳定性不再是一个系统需要满足的条件。

英文摘要:

This paper presents an analysis of the modified L1 adaptive control law. The performance of this control law is compared to the original control law. The modified L1 control law uses the DC gain of the transfer function of the closed loop plant dynamics. There is slight worsening of the controller performance. Furthermore, this analysis shows that provided that there is room for slight performance reduction, L1 adaptive control law can be used to control non-minimum phase systems without the use of a pole-zero cancellation technique. L1 adaptive control requires five assumptions before it can be applied. The stability of matched transmission zeros is no longer a condition that a system needs to meet as a result of this modification to the adaptive control law.
