Output feedback H-infinity control for linear discrete-time systems with closed-loop disk pole constraints
线性离散系统具有闭环极点约束的输出反馈H∞ 控制

The problem of output feedback H-infinity control with closed loop disk pole constraints was considered for linear discrete time systems. The existence condition and design procedure for the desired output feedback controllers were presented via the linear matrix inequality (LMI) approach. Compared with the existing results, the proposed one is of less conservatism.
