DC-Motor Control Using Arduino-Uno Board for Wire-Feed System

A speed-controlled dc-motor chopper drive of wire- feed mechanism implemented by Arduino-Uno board is presented in this paper. This drive system is characterized as high static and viscous frictions load, even more it features a variable moment of inertia. Thus, the speed regulator with internal current loop should be carefully designed. Therefore, PI- speed and current regulators design should be fulfilled at limit values that wire-feed mechanism inertia can be taken to insure the stability. Finally, the obtained controllers are discretized and implemented. The experiment results exhibit sufficient agreement in term of transient response and stability which justifies the ability of introducing microcontroller-based Arduino in industrial applications.
