Real time digital simulation (RTDS) software and hardware in the loop (HIL) architecture for brushless DC motors

This paper presents a new approach for the real-time digital simulation and hardware in the loop support for brushless dc motors. Sampling theory is used to model the interaction between the digital simulator infrastructure and the motor controller. A 6-step Voltage Source Inverter (VSI) is used as an illustrative example for the hardware in the loop and the results are compared with the Matlab Simulink results of brushless dc motor.
