This article describes the creation of a low-cost, real-time simulator of several control strategies for brushed DC motor drives. An educational brushed DC motor drive test bench and an Arduino Mega 2560 microcontroller board were used to build the simulation system. The system can serve as a platform for laboratory studies in which various control strategies helpful for instruction and research are designed and tested. The interaction between Simulink and the Arduino board in this study is managed via the MathWorks Arduino IO Package. For configuring and gaining access to Arduino sensors, actuators, and communication interfaces, the target comes with a library of Simulink. Different speed control algorithms for brushed DC motors can be easily deployed, monitored, and analysed using Simulink's multiform library. Three different types of controllers have been used in this study: a standard PI controller, a fuzzy logic controller, and a fuzzy PI controller. Finally, the system is particularly helpful in comparing various control approaches for many other controlled objects in addition to drives for brushed DC motors.
