摘要
研究一类非线性系统故障诊断与容错控制的集成设计问题。针对执行机构故障,结合反馈线性化理论、不变集理论以及鲁棒H∞控制理论,提出一种对执行机构故障具有完整性,并且能够迅速准确地诊断并隔离故障的故障诊断与容错控制集成设计方法。为了提高闭环控制系统的动态性能,完成了控制回路的极点区域部署设计。将该方法应用为卫星姿态控制系统的故障诊断与容错控制集成设计,仿真证明了该方法的有效性。
A method for designing integrated fault diagnosis and fault-tolerant control（ IFDFC） is proposed in this paper for a class of nonlinear systems. The solution of this problem is obtained by employing invariant ellipsoidal sets,feedback linearization and robust H∞control theory. To optimize the transition performances of the close-loop systems,a D stable analysis for the controller based on LMI is given. At last,the simulation of applying in a satellite attitude control system with actuator faults validates that this solution is effective.
