Abstract:
This paper explores the model reference adaptive control problem for a class of switched linear systems under arbitrary switching with no need for the measurability of the system state. Based on the state of reference model and the measurable output error, adaptive laws and controllers are designed for switched systems. Each subsystem may have its individual reference model and controller, which increases the design flexibility. The introduction of the closed-loop reference model is to get a better transient performance of the whole switched systems. A numerical example is provided to verify the effectiveness of the main results.

任意切换下基于闭环参考模型的切换系统的自适应控制

摘要:

本文研究了任意切换下一类线性切换系统的模型参考自适应问题,对于被控系统的状态可测性没有要求。控制器和自适应率的设计依赖于参考模型的状态和可测的输出误差。每一个子被控系统都有自己单独的参考模型和控制器,这增加了设计的灵活性。闭环参考模型的引入可以使得整个切换系统的暂态性能得到提升。最后一个仿真实例验证了本文结论的有效性。

研究目的:

一类切换系统在任意切换下的稳定性

研究方法:

模型参考自适应控制方法,共同Lyapunov函数法

研究结果:

误差切换系统最后状态趋于0,即被控系统的状态轨迹跟踪上了参考模型的轨迹。

结论:

一类切换系统在任意切换下的模型参考自适应问题得到解决,其参考模型是闭环参考模型,每个子系统都有自己的参考模型和控制器,通过调节闭环增益提高了系统的暂态性能。
