| Abstract: |  For the purpose of effective diagnosis of a class of nonlinear system with the time-varying failure of the actuator, a method of the fault accommodation was proposed based on time-varying gain extended state observer (ESO) for the inverse system.  Firstly, the traditional constant gain ESO was improved by using a time-varying gain design method, which guaranteed that the  |
