摘要：

This paper describes a sensor fault diagnosis algorithm for a class of nonlinear dynamic systems. The main idea behind this approach is to monitor the closed-loop system for any off-nominal system behavior due to sensor faults utilizing a nonlinear on-line approximator with adjustable parameters. A nonlinear estimation model and learning algorithm are described so that the on-line approximator provides an estimate of the sensor fault. The robustness, stability and learning performance properties of the nonlinear sensor fault diagnosis scheme are established.
