The Application Of MCU For Fault Diagnosis In The Actuator's Feature Extraction

Actuator is one of the main reasons that cause to fault occurrence in the automatic control system at the present, because of actuator work at bad environment and its importance, so it is very important that fault diagnosis of actuator.This text with electric actuator for example, put forward a kind of method that make use of MCU realization to fault diagnosis.At the first detail set forth the work characteristic and principle of electric actuator , at the base of depth analysis mechanism and performance of electric actuator .Then verify on above analytical through the fault experiment .due to the special of the constant gain failures,this text put forward a kind of new diagnosis method.At last design the MCU system that with AT89S51 MCU for the core carry out data acquisition of the fault characteristic , According to of the analysis of data acquisition of the fault characteristic realize the fault diagnosis of the electric actuator.
