Equivalent hardware representation of pm synchronous machines realized by a physics-based machine model for hardware-in-the-loop simulation applications

This paper presents an approach to realize an equivalent hardware representation of PM synchronous machines through a physics-based machine model for hardware-in-the-loop simulation of PWM drives. The equivalent hardware representation of the machine is achieved using a controllable load. The load current is controlled to be the same as the currents obtained over the physics-based model of the machine. The physics-based model of the machine is built using parameters obtained from the solutions of the transient FE computation covering a complete AC cycle. The modeling of the machine in such a way includes the details of machine design and their impacts on the machine performance during its operation. The presented work introduces a new method to perform the HIL-based machine control experiment studies before the actual fabrication of the machine or under the circumstances where the direct use of the actual machine is unavailable.
