Webobservers have been presented in the literature (e.g., [13, 35, 40]). In this chapter, we will study this topic and provide a design procedure to construct unknown input observers. This will generalize the state-estimators that we studied in Section 2.8, and will turn out to be quite useful in diagnosing system faults, as we will see later. WebDownloadable (with restrictions)! In this paper, the fault estimation problem is considered for nonlinear system with process fault, sensor fault and unknown input. A novel adjustable dimension augmented descriptor observer is designed. Based on the proposed observer, the system state, process and sensor faults can be estimated simultaneously, and the …
