Língua de trabalho

Portuguese - Suitable for English-speaking students

Objetivos

Students should be able to:

• Understand the difference between open loop and closed loop (feedback) systems and identify the components of a feedback control system.
• Analyze the transient response and steady state behavior of linear systems.
• Understand the concept of stability of control system and methods of stability analysis.
• Understand basic applications of proportional, integral and derivative feedbacks in control systems and their effects on the system performance and stability.
• Apply the root locus method, PID tuning rules, Feedforward control, Cascade control, Ratio Control. Internal model control (IMC) and multivariable control methods to analyze and design linear feedback systems.
• Analyze and design control systems using Matlab/Simulink software.

Métodos de ensino e atividades de aprendizagem

In the classes, fundamental concepts are exposed, using audio-visual techniques. Illustrative applications of these concepts are solved, stimulating rational thinking and fostering a more critical spirit amongst students. In these same classes the students also solve application exercises, individually and independently.

Fórmula de cálculo da classificação final

Evaluation:

a) Continuous
– 2 tests with 90 minutes duration. Each test has a 50% weight in the final evaluation.

b) By exam
– Final exam with 100% weight in the final evaluation.

In cases considered convenient, an oral assessment can be carried out for all students with a rating higher than 9.5. In this situation, the final classification will be the oral exam.
