Real-Time Controller-Hardware-in-the-Loop Testing of DC Motor-Drive Systems

Abstract

This paper aims at validating and per- formance testing of the real-time models for Direct Current (DC) motor-drive systems using Controller- Hardware-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 μs is achieved. The closed-loop control scheme is based on adjusting the angular velocity of the DC mo- tor by controlling the armature current, which in turn, controls the developed electromechanical torque of the DC motor. Implementation and performance verifica- tion 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 real- time implementation and performance verification of DC motor-drive systems using the C-HIL testing plat- form to show perfect concordance with the machine the- ory without the need for costly commercial real-time simulators.
