A HIL-based DC Motor Speed Control

This document presents a HIL based DC motor speed control. In this paradigm the controller is implemented as a physical system handled by a IGBT based on a PI control using a microcontroller’s PWM outputs. The controller receives the setpoint which is established based on the power system frequency simulated. This is modelled using OPAL-RT Simulink® for the real time simulation allowing the motor to deliver an adjusted mechanical torque feeded into a synchronous generator coupled with the controlled CD motor which in this case is used as a prime mover. Therefore, the controller achieves to control the real power feeded into the simulated electrical power system to control its frequency.
