摘　　要：针对以往研究的连续系统中没有同时考虑多个状态滞后和执行器故障的情况,对带有多个状态滞后的连续系统进行了研究.通过理论分析得出了这类系统渐近稳定且扩展严格正实的充分条件.在此基础上,对这类系统存在不确定性和执行器故障的情况进行了研究.结果表明,所设计的正实控制器能够保证闭环系统对容许不确定性及执行器故障都是渐近稳定和扩展严格正实的.同时,通过实例分析,说明所提出的正实控制器设计方法可行且有效.The conditions of multiple state-delays and actuator failures weren＇t simultaneously considered in former research.The continuous system with multiple state-delays was researched.The sufficient condition that this class of system is asymptotically stable and extendedly strictly positive real was deduced by theoretical analysis.On the basis of it,this class of system with uncertainties and actuator failures was researched,and a positive real controller was designed.It ensured that the close-loop system is asymptotically stable and extendedly strictly positive real against facultative uncertainties and actuator failures.Simultaneity,an example was analyzed to show that the proposed design approach of positive real controller is feasible and effective.
