  • Abstract
    A fault detection filter is designed by minimising the response to confounding noises whilst keeping the fault response constant. A linear quadratic optimisation problem, related to ℋ2 and ℋ ∞ optimal control is used. The “Q” matrix of the associated Riccati equation is indefinite in contrast to the indefinite “R” matrix of ℋ∞ control. We extend linear optimal control theory to solve the fault detection problem in this framework
