Abstract

It is argued that, when a singularly perturbed proper plant is preceded by a zero-order-hold, the direct and the induced direct (resulting from neglecting unmodeled high-frequency dynamics) transmission terms of the reduced-order model should be treated as two distinct terms; the latter contains a delay element and the former does not. It is shown that the observer-based sampled-data controller for the reduced-order model can stabilize the original plant for sufficiently small values of the singular perturbation parameter.<>
奇异摄动系统的鲁棒观测器稳定器:采样数据控制方法
本文认为,当奇摄动固有对象前面有零阶保持器时,降阶模型的直接传输项和诱导直接传输项(由于忽略未建模的高频动力学)应被视为两个不同的项;后者包含延迟元素,而前者没有。结果表明,对于降阶模型,基于观测器的采样数据控制器可以在奇异摄动参数足够小的情况下稳定原对象。
