Fault Tolerant Control for Networked Control Systems with Access Constraints
摘要
Abstract
In this paper,the problem of fault tolerant control (FTC) considering actuator fault for networked control systems (NCSs) with access constraints is addressed.A static scheduling method,periodic communication sequence (PCS),is applied to allocate network resource and schedule the access to the network.The novelty of this work lies in that the NCS with PCS and actuator fault are modeled as a periodic switching system and the schedule-dependent Lyapunov function method is used to design the fault tolerant controller.For the data packets dropped by scheduling strategy at each sampling time,0 and the value of previous sampling time are respectively considered to recover them.Additionally,the problem of robust FTC for the controlled plant with external energy-bounded disturbance is also respectively discussed under these two situations.Numerical examples are given to illustrate the effectiveness of the proposed design methods.关键词
