论文摘要
本文提出了一种新颖的参考调查方案，用于跟踪控制系统中的缓解措施。我们提出的计划，被称为具有动态约束（RG-DC）的参考调查员，将过冲的缓解问题重新提出为约束管理问题。该重新印象的结果是动态最大可允许的集合（MAS），该集合随参考信号和跟踪输出的函数而实时变化。 RG-DC采用动态MAS来修改参考信号以减轻，或者在可能的情况下防止过冲。我们介绍了动态MAS的几种属性和计算它所需的算法。我们还研究了RG-DC的稳定性和递归可行性，并介绍了RG-DC对其对管辖系统频率响应的影响的有趣属性。仿真结果证明了该方法的功效，也强调了其局限性。本文是我们有关此主题的早期论文的延伸。
This paper presents a novel reference governor scheme for overshoot mitigation in tracking control systems. Our proposed scheme, referred to as the Reference Governor with Dynamic Constraint (RG-DC), recasts the overshoot mitigation problem as a constraint management problem. The outcome of this reformulation is a dynamic Maximal Admissible Set (MAS), which varies in real-time as a function of the reference signal and the tracking output. The RG-DC employs the dynamic MAS to modify the reference signal to mitigate or, if possible, prevent overshoot. We present several properties of the dynamic MAS and the algorithms required to compute it. We also investigate the stability and recursive feasibility of the RG-DC, and present an interesting property of RG-DC regarding its effect on the governed system's frequency response. Simulation results demonstrate the efficacy of the approach, and also highlight its limitations. This paper serves as an extension of our earlier paper on this topic.
