摘　　要：研究了被控对象和控制器均存在不确定时闭环系统鲁棒稳定性和非脆弱控制问题,分别讨论了左互质因子摄动和右互质因子摄动情况下反馈系统的非脆弱鲁棒稳定性和性能敏感性问题,并给出了相应条件下系统非脆弱鲁棒稳定的充分条件,最后给出了两种情况下系统非脆弱鲁棒稳定性之间的关系。The problem of the robust stability and non-fragile control of closed-loop system was studied for the system with structured uncertainties both in plant and in controller. Non fragile robust stability and performance sensitivity of the closed loop system with left coprime fac tor perturbations and right coprime factor perturbations were investigated separately, and the sufficient conditions were given for the non-fragile robust stability of perturbed system under cer tain conditions as well. At last the relation of non-fragile robust stability between the two aspects was given.
