Robust fault estimation of discrete-time nonlinear system based on an enhanced maximum-priority-based switching law

The problem of robust fault estimation of discrete-time nonlinear plant is investigated from the view of reducing its conservatism and restraining its on-line computational burden simultaneously. Firstly, an enhanced maximum-priority-based switching law is developed for subdividing the distribution types of normalized fuzzy weighting functions in a more flexible way. Then, a new fuzzy fault estimation observer is proposed with different...
