Title: Study Of Parameter Monitoring In Stationary Mechanical Systems
Author: Chiarello A.G.
Pederiva R.
Abstract: This work describes a method of parameter monitoring in stationary mechanical systems for fault detection and location purposes. Using a state space model of the system and an auxiliary one, called filter, analytical redundancy equations are defined. The redundancy equations are based on correlation functions involving systems parameters. It is demonstrated that these correlation functions can be used to generate residual functions for fault monitoring. All residual functions estimated for the healthy system are ideally zero but when a fault occurs, some estimated residuals differ from zero. Using a parametric residual analysis, one can locate the physical parameter that is directly related to the system fault. The proposed approach is demonstrated using a numerical example.
