Abstract
An electrical machine drive system is simulated with a circuit simulator to model normal operation, fault modes and control strategies for electric motor based vehicles. The electrical machine drive system includes a DC power source model ( ), an inverter model ( ) and an electrical machine model ( ). The system is modified through substitution of components or removal of components to simulate faults. Post-fault control strategies are implemented in a similar manner and simulated. The model and methods associated therewith reduce modeling complexity and reduce simulation time, permitting thorough design and analysis of electric motor based vehicles.
