Design of Real-time PID tracking controller using Arduino Mega 2560for a permanent magnet DC motor under real disturbances

Abstract

The most widely used control strategy in industry is proportional integral derivative (PID) controller. The popularity of PID controllers can be attributed partly to their robust performance in a wide range of operating conditions and partly to their functional simplicity. One of the applications is to control CNC cutting machine model by using permanent magnet DC motor as actuator. In the current work, we contribute to present the design of Real-time PID tracking controller using Arduino Mega 2560 for a permanent magnet DC using Matlab with the intention to both illustrate graphical interface properties using (Matlab GUI) and display the responses of DC motor controlled through PID in real time under real constraints and disturbances. Furthermore, we implement it to the selected Arduino by using Support Package for Arduino Hardware in MATLAB. The speed control implementation of permanent magnet DC motor based on Arduino mega 2560 and L298N H-Bridge as alimentation using PID control method has been validated by experiments on the physical system. Practical results are presented to demonstrate the effectiveness and advantage of the system control scheme in Matlab in real time. Performance analysis shows the effectiveness of the proposed control scheme in real time.
