Abstract :
Optimal methods for designing observers used for fault detection have been proposed in Viswanadam and Minto (1988). Since then, many authors have presented different design methods, most of them based on the H∞ technique. In this paper, a procedure for designing an l∞ optimal observer is presented, where the optimal observer is obtained from the solution of a linear programming (LP) problem. As a measure of the sensitivity of the fault detection scheme, the minimum detectable fault and maximum undetectable fault are evaluated
