Fault-tolerant Control of Linear Singularly Perturbed Systems with Applications to Hypersonic Vehicles ?

摘要

This paper studies the fault-tolerant control (FTC) problem of linear singular perturbed systems with component faults. Based on the analysis of two decomposed lower-order subsystems, a composite fault-tolerant controller is designed to asymptotically stabilize the original impaired system through cooperative regulation of the control gains. An application to the longitudinal control system of a hypersonic vehicle with actuator faults is given. The singularly perturbed model of such a system is derived and a composite fault-tolerant controller is designed, which illustrates the effectiveness of the proposed method.
