摘要

本文以正系统理论为基础,针对一类线性系统提出了一种新的规定性能保证控制(PPC)。与标准 PPC 结构不同,我们关注的重点是受约束状态与相关性能边界之间距离的正向性。原始受限系统被映射为涉及距离的切换正系统。这种新颖的框架减轻了控制器的脆弱性/敏感性,因为它消除了高增益机制产生足够控制输入以防止违反约束的必要性。它在很大程度上拓展了性能边界,无需辅助结构即可实现各种预定的性能行为。理论分析和数值模拟都阐明了所提方法的有效性。

Prescribed Performance-Guaranteed Tracking Control: A Switched Positive System Perspective
This letter presents a new prescribed performance-guaranteed control (PPC) for a class of linear systems based on positive system theory. Different from standard PPC structure, our attention focuses on the positivity of distance between constrained state and associated performance boundaries. The original constrained system is mapped to a switched positive system involved in distance. This novel framework mitigates the vulnerability/sensitivity of the controller, as it eliminates the necessity for high-gain mechanisms to generate sufficient control input against constraint violations. It develops the performance boundary to a great extent, where various predetermined performance behaviors could be achieved without auxiliary structure. Both theoretical analysis and numerical simulation clarify the effectiveness of the proposed approach.
