Fault Diagnosis of Electric Actuator in the Thermal Power Plant Based on Data-Driven

Abstract

Because the past fault diagnostic methods of electric actuator are mostly taken in the control system, and tend to cover up the implementation of the fault itself, and the constant gain fault of actuator is not easy to determine. In response to these shortcomings, The mechanism of the actuator is analyzed in this paper , in order to identify the effective measuring points electric of actuator. A approach based on data-driven to the implementation of the provision of the signal itself to deal with failures is processed and to establish the fault diagnosis system. The method is not only need to establish a complex mathematical model but also with the advantage that need a simple calculation to determine the fault quickly.
