摘　　要：把基于积分二次约束H∞可靠性控制方法引入状态与时滞不确定系统。通过LMI方法导出无扰动时滞系统具有二次约束H∞可靠性控制的时滞依赖标准,降低有关判定系统鲁棒稳定性条件的保守性。通过推导获得参数与时滞不确定系统的时滞依赖标准。通过数例说明所得结论。H∞ reliable control with integral quadratic constraint （IQC） performance for a class of uncertain systems with state and input delays is considered in this paper. At first it is given that a delay- dependent criterion for time- delay systems without perturbations being designed H∞ reliable control with iQC performance through LMI approach. Next, a criterion for uncertain time - delay systems with parameter uncertainties is obtained via simple derivations. The obtained conditions detract the conservative of the conditions in relation to the robust stability of systems. Finally, a numerical example is given which illustrates the effectiveness of the proposed result.
