摘　　要：在研究一类多时滞主从混沌系统的鲁棒非脆弱H!容错同步控制问题的基础上,针对混沌系统无故障和故障这两种情况,分别设计了非脆弱控制器和非脆弱容错控制器。运用Lyapunov函数理论验证了混沌同步误差系统的稳定性,同时得到了系统渐近稳定及满足指定H!性能指标的充分条件。仿真对比分析证明了系统故障估计算法的有效性和可行性。The issue of robust non-fragile H∞ fault tolerant synchronization control for master-slave type chaotic systems with multiple time delays is researched. In accordance with the conditions of chaotic system both without failure and in fault, the non-fragile controller and nonfragile fault tolenrance controller are designed, and the stability of chaotic sycbronization error system is verified by adopting the theory of Lyapunov function, in addition, the sufficient conditions of the system asymptotical stability and satisfying specified performance index are obtained. The effectiveness and feasibility of the algorithm are illustrated by simulation and comparative analysis.
