Hi.
I'm a graduate research and teaching assistant in one of the top engineering universities of Turkey (Middle East Technical University). I assisted the control system courses and planned the laboratory sessions. In one of these labs, I asked the students to identify a DC motor and to design PID and LQR controllers, which is exactly your project. That is, I'm quite familiar and I have all the necessary tools and knowledge to help you with your project. In addition, I'm consulting a company as a senior control system designer with my 7+ years of experience in control systems. As well as these working experiences, I also have my MSc degree in control systems, and currently pursuing my Ph.D. in the same field.
I can assure you that I can complete every task in your project with %100 success on time. Please let me know if you need any further information.
Stay healthy.
