Modeling and fault simulation analysis of triplex redundance servovalve

摘要

The paper is based on the technological transformation project from a certain institute. The objective is to test the stability and reliability of the triplex redundance servovalve. Considering the complicated structure and the basic principle of triplex redundance servovalve, the mathematical model of the valve is established. Based on the mathematical model, the performance of the triplex redundance servovalve when faults appear can be simulated and analysed. The faults include the coil disconnection and current full bias.
