Give students knowledge about PID controllers and their tuning and the ability to identify the need or opportunity for application in real processes.
1 -Students should be able to understand open loop and closed loop (feedback) systems and identify the components of a feedback control system.
2 - Students should be able to analyze the transient response and steady state behavior of linear systems.
3 - Students should be able to understand the concept of stability of control system and to apply methods of stability analysis.
4 - Students understand basic applications of proportional, integral and derivative feedbacks in control systems and their effects on the system performance and stability.
5 -Students should be able to do the tuning of a PID controller using the tuning methods learned in the classroom
6 - Students should be able to analyze and design control systems using Matlab/Simulink software.
1-Mathematical modeling of physical systems- Transfer function. Poles and zeros. Block diagram reduction techniques.
2-Time response of first and second order systems– time domain specifications. Types and order of systems, steady state errors.
3-Scope of control, Parts of a control system. Open and closed loop systems. Advantages of closed loop operation: Sensitivity and complementary sensitivity, disturbance and noise reduction
4-Stability of Control System- Location of roots in S plane for stability.
5–PID Controllers-Proportional, Integral and Differential Elements. Effects on system response. Ziegler-Nichols PID tuning rules. Reset-windup. Real system applications.
Theoretical-Practical Classes: Introduction of concepts with presentation of examples. Solving exercises by students. Support texts and exercises that contribute to the acquisition of the expected knowledge and skills are provided to students.
Laboratory Classes: Computer simulation of systems and analysis of their responses over time, using MATLAB and SIMULINK programs. Simulation of systems with behavior similar to those of physical systems existing in the laboratory. Identification of models of real systems. Controller parameter tuning experiments. Parameterization of industrial controllers.

1 - The assessment has two components, a theoretical-practical component (NTP) and a laboratory component (NLAB).
2 - To be approved, the student must have an average equal to or greater than 9.5 in tests (NPT) and in the laboratory (NLAB).
3 - In the theoretical-practical component, instead of tests, the student can choose to be assessed by exam.
4 - There will be two evaluation tests, face-to-face (50% each), which for approval require an average grade higher than 9.5. This will be called the theoretical grade (NTP).
5 - In the laboratory, individual oral tests will be performed to evaluate the skills acquired in the CU, with special emphasis on the subjects taught in the laboratory classes. Practical tests may also be performed to assess the skills acquired in the course, with special focus on the subjects taught in laboratory classes.
7 - In case of failure in the tests (NTP<9,5), it is foreseen the possibility of a recovery test to one of the tests, to be held on the date of the first exam.
