Abstract
In this chapter, inspired by the previous work, our objective is to provide a general robust fault estimation observer scheme with finite-frequency specifications for continuous-time systems. Main contributions of this chapter are twofold: (1) Based on the generalized KYP lemma, a multi-constrained FFEO with finite-frequency specifications is proposed to achieve fault estimation, aimed at decreasing the conservatism that results from the entire frequency domain; (2) By using the projection lemma and introducing auxiliary slack variables, we obtain the improved results, which not only design different Lyapunov matrix for each constraint, but also are convenient to calculate FFEO parameters for different frequency domains.
