H_∞ State-Feedback Control of Discrete-Time Systems with Norm-Bounded Time-Varying Uncertainty

本文对具有有界时变不确定性的离散时间系统的H∞状态反馈控制问题进行研究．导出了H∞干扰衰减约束下系统二次稳定的充分条件，给出了一种基于离散代数Riccati方程的带观测器的鲁棒H∞状态反馈综合方法．

This paper focuses on the Had state-feedback control of discrete-time systems with norm-bounded time-varying uncertainty. We derive sufficient conditions for quadratic stability which is subject to H∞ disturbance attenuation constraint,and present an observer-based robust H∞ state-feedback synthesis method based on the use of discrete algebraic Riccati equations.
