Fault Tolerant Scheme of Switched Reluctance Machines for the Electro-Mechanical Actuation Systems

Article Preview

Abstract:

As switched reluctance machines (SRM) generally offer a simple and robust design, they are very suitable for electromechanical actuation systems which need to be actuated by fault tolerant drives. This paper investigates dual-channel, dual-redundancy, lacking phase schemes of SRM guaranteeing fault tolerance and the corresponding control systems in detail are compared to point out the advantages and disadvantages of them., a new lacking phase scheme for 12/8 SRM is proposed and the finite element model based on field-circuit coupling is established, results indicate that this scheme have superior fault tolerant performance and suit tasks in electro-mechanical actuation system of aerospace environments.
