英文摘要

      This paper focuses on the H∞ 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.
