摘　　要：研究了具有复制执行机构的不确定非线性系统的 H∞ 状态反馈可靠控制 .用耗散理论 ,基于 Hamilton- Jo-cabi不等式 ,得到了非线性 H∞ 状态反馈可靠控制问题可解的充分条件及控制器的设计算法 ,使得当有执行机构失效时 ,闭环系统仍渐近稳定且 L2 增益有限 .WTBZThis paper is concerned with the reliable state feedback controller design problem for a class of uncertain nonlinear systems with duplicated actuators. By using dissipative theory, a procedure of designing reliable nonlinear controller is presented on the basis of solutions of the Hamilton-Jacobi inequality. The resulting closed-loop system is reliable in the sense that the performance(i.e., internal stability and H ∞ attenuation) of the closed-loop system is guaranteed not only when all actuators are operational, but also when some actuator outages occur.
