Residual Generation with Enhanced Robustness Against Model Uncertainties
Chapter 8 is dedicated to the most challenging topic on the mode-based residual generation, that is, residual generation based on a model with uncertainties. To this end, preliminary knowledge of advanced LMI technique and stability of systems with stochastic uncertainties is first introduced. The core of this chapter is the reference model based residual generation strategy, in which the unified solution presented in Chap. 7 serves as the reference model delivering a reference residual signal. The residual generator design is then realized on the basis of a minimization of the difference between the reference and real residual signals. This strategy is applied to the FDF design for systems with norm-bounded uncertainties, polytopic uncertainties, and stochastic uncertainties.
