# Observer-based Robust Fault Diagnosis - Logic-dinamic Approach

### Alexey N. Zhirabok, Alexey Ye Shumsky, Alexey Yu Suvorov

#### Abstract

The problem of robust fault detection and isolation in robotic and mechatronic systems described by nonlinear models with non-smooth nonlinearities is considered. So-called logic-dynamic approach to construct the diagnostic observer with non-smooth nonlinearities by linear methods is considered. The method which allows obtaining full set of solutions with minimal sensitivity to the disturbance is suggested. This set of solutions can be used to choose the optimal solution with maximal sensitivity to the faults.
