Robust absolute stability of interval discrete-time Lurie systems
区间离散Lurie系统的绝对稳定性

The problem of robust absolute stability for interval discrete_time Lurie systems containing an arbitrary number of monotonic sector bounded memoryless time-invariant non-linearities is researched by Lyapunov function, an algebraic sufficient condition with interval matrix inequlity form is obtained for the interval discrete_time Lurie system, and relationship between the stability of interval symmetry matrix and this criterion is established.
