Research on Fault Analysis and Fault-tolerant Control of Valve Electric Actuator System Based on SRM

摘要：

As the requirements of nuclear power plants, electric actuator valve based on SRM can meet the poor working environment of nuclear power plants. However, low failure rate and fault tolerance decided the performance of valve electric actuator system based on SRM. This paper analyzes the fault characteristics of valve electric actuator system based on SRM. To realize fault operation when system is fault caused by power converters switch normally open and normally closed, a fault-tolerant control method which has got a good control consequent was proposed. The fault simulation circuit and fault-tolerant control algorithm in Matlab / Simulink was set up to verify the fault-tolerant control method of the power converter under fault conditions.
