A Low-Cost Real-Time Simulator Of Fuzzy Logic Control For Brushed Dc Motor Drives

Abstract

This article describes the development of a low-cost, real-time simulator of several control strate- gies 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 strate- gies helpful for instruction and research purposes. The interaction between MATLAB Simulink and the Ar- duino board can be managed through the exploration of the MATLAB Support Package for Arduino. Dif- ferent speed control algorithms for brushed DC motors can be easily deployed, monitored, and analysed using the Simulink 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.
