Abstract
This chapter presents a new methodology of quantitative evaluation of the resiliency of electric traction drive which consists of the multilevel electric energy inverter and multiphase electric motor. It is proposed to consider such propulsion system as a system with a few states with degraded values of performance. As a complex indicator for resiliency estimation, it is suggested to take the criterion of degree of resiliency. For the approbation of the suggested method, the application case for assessment the resiliency of the traction train of an electrical helicopter was provided. The application results show that for design requirements on the value of reliability and resilience of electrical helicopter’s propulsion system in operational conditions of the real flight only presented topology of multiphase electric motors in combination with multilevel electric inverters fully meet the project requirements without restriction. The presented methodology can be used successfully as a convenient tool for quantitative estimation and optimization of the degree of resiliency for safety-critical propulsion systems.
