H{sub}∞ Detection Filter Design for State Delayed Linear Systems

摘要

This paper studies the problem of H{sub}∞ detection filter design for state delayed linear continuous-time systems, in which the effects of faults and unknown inputs, including model uncertainties and external plant disturbances, cannot bedecoupled from each other. The detection filter gains are designed so that if the fault of the system is absent, the filter is convergent. The transfer function from disturbances to residual satisfies the prespecified constraint of H{sub}∞ norm upperbound. The design freedom can be used to reach an extreme value of sensitivity of the residual to faults.
