Prakties 2 - Electrical, Electronic and Computer Engineering

7. Report
The report must be written in English and include the following:
1. Design of the PID controller with the Cohen-Coon method.
2. Design of the controller with the Ziegler-Nichols oscillation method.
3. Component values calculated for realisation of the controllers.
4. The measured , and steady-state-error values from the simulations as well as from the
practical results.
5. Comparison of these values for the simulation and practically implemented controllers.
6. PSpice or Simulink simulation of the closed loop systems.
7. Discussion of results.
8. A conclusion.
8. Demo
The demo will be based on the following:
1. Lab books with completed preparation assignments.
2. Closed loop response of the implemented Cohen-Coon based PID controller.
3. Closed loop response of the implemented Ziegler-Nichols based PID controller.
4. Performance measures achieved ( , and steady-state-error) for the practical controllers.
5. Answering of questions.
(Note: Please build the Cohen-Coon and Ziegler-Nichols controllers separately such that they can be
interchanged easily in the demo. They should however be implemented on the same plant).
