Arduino based control test set design usable in matlab simulink environment

DC Motors are frequently used in applications requiring position and speed control due to their high torque capacities at low speeds. When satisfactory results are not obtained when the open loop is controlled, they are controlled as closed loop. PID controllers are used to control DC motors in applications that do not require high precision. PID control is widely used in industrial control and therefore it is important to determine the PID parameters that have a large impact on the output value. The PID Controls object can be used to find PID coefficients using the PID Tuner interface program. Designed for easy use by users, the Arduino microcontroller is widely used in real-time control applications. Using the Arduino motor drive, the DC Motor is operated at the desired PWM value. In this thesis, simulation and real-time behavior of a DC Motor in Matlab-Simulink environment are investigated by using mathematical parameters obtained from various measurements and experiments. Simulink simulation model of DC motor drive system is made and the obtained results are compared with real time experimental model. Using the simulink model for real-time control, real-time control of the DC Motor connected to Arduino microcontroller is provided by PWM (Pulse Width Modulation) control signals. Measured speed information is passed through PID controller and the speed of DC Motor is controlled. PID coefficients determined in simulation environment were applied to real time control. The results were compared with the results obtained in the simulation environment. Furthermore, the speed (rpm) results obtained by using PI and PID controllers in real time control of DC Motor were compared. The performance of the controllers were compared using different criteria such as ISE, ITSE, IAE and ITAE. Since DC Motor is preferred in system modeling studies and is easily accessible to users, this experiment set has been prepared for students, teachers and other users.
