Faculty of Electrical and Computer Engineering - Spring 2020

This assignment had two parts.

In this part, three different linear systems were analyzed using MATLAB.

In this part, the differences between open-loop and closed-loop versions of a specific system were analyzed. I compared the speed of reaching the settle condition of each of them while using a specific value for the Tao parameter and in the next step, the stability of the open-loop and the closed-loop systems were evaluated.

In this assignment, a DC motor with the physical parameter mentioned in the last table of the "Modeling and Simulation of DC Motors.pdf" file was created and analyzed using Simulink.

In this assignment, first, by using MATLAB I launched a DC motor by given parameters. Second, I found the width of the dead zone of the simulated DC motor. And in the final step, the transition function of the DC motor by analyzing the step response of the system was identified successfully.

In the final assignment, the transition function of the input voltage of the motor to the speed of the motor was simulated in MATLAB. Then, the effect of the proportional, proportional-integral(PI), and lag compensators on the speed of the motor was analyzed. Finally, the proportional, proportional-integral(PI), and lag controllers for controlling the speed of the motor were simulated and compared.
