REAL-TIME CONTROLLER-HARDWARE-IN-THE-LOOP TESTING OF DC MOTOR-DRIVE SYSTEMS

This paper aims at validating and performance testing of the real-time models for Direct Current (DC) motor -drive systems using ControllerHardware -in -the -Loop (C-HIL) platform. The DC motor -drive systems are modeled in real-time using STM32F4 Discovery kits, where a minimum time -step of 10 mu s is achieved. The closed -loop control scheme is based on adjusting the angular velocity of the DC motor by controlling the armature current, which in turn, controls the developed electromechanical torque of the DC motor. Implementation and performance verification of DC motor -drive systems and the controller can be time-consuming and expensive. The main objective of this paper is to demonstrate the practicality of realtime implementation and performance verification of DC motor -drive systems using the C-HIL testing platform to show perfect concordance with the machine theory without the need for costly commercial real-time simulators.
