摘要: Abstract The problem of non-fragile H∞ filtering for a class linear systems described by delta operator with circular region pole constraints is investigated. purpose the paper to design filter such that error system not only satisfies prescribed or D-stability constraint, but also meets norm constraint on transfer function from disturbance input estimation error. gain be designed assumed have multiplicative variations. A sufficient condition existence obtained using appropriate Lyapunov and matrix inequality (LMI) technique. numerical example provided demonstrate effectiveness less conservativeness proposed design.
