摘要: 本文以时变时滞系统为研究对象，引入H∞扰动衰减度γ（H∞disturbance attenua-tionγ）为性能指标，设计时变对象的无记忆鲁棒控制器，使系统在固有时变特性和外部扰动影响条件下保证闭环稳定且具有H∞扰动衰减度γ，并讨论控制律解的存在条件．文中考虑的时滞对象具有多重状态滞后，时滞变化率小于1．Abstract: This paper studies time-varying systems with multi-delays in state,The H∞ disturbance attenuation γ is introduced as the performance norm firstly,Then a memoryless feedback controller is designed to ensure that the close-loop system is stable with H∞ disturbance attenuation γ.The condition under which the controller exists is discussed also.
