Objectives

The fundamental objective of this course is to develop competences on modeling, analysys and design of automatic control systems for physical/chemical/biological processes. As a complement, it is exepected that the students will gain basic knowledge on instrumentation associated to automatic control: sensors,  controllers, and final control elements.

Learning outcomes and competences

A student, after successfully concluding this course, should be able to:

• Create mathematical models based on differential equations for representing dynamic systems.
• Linearize non-linear dynamic system models in the neighborhood of a steady-state.
• Create bloc diagrams for linear dynamic systems, identifying the intervening transfer functions.
• Identify the main instrumentation used in process control of physical/chemical/biological processes.
• Design and tune classic controllers according to given performance criteria.
• Design and tune some advanced control strategies, performing a critical analysis of their pertinence.
• Recognize the main methods for treatment of analog and digital signals.

Working method

Presencial

Program

The main topics in this course are:

1. models of dynamic systems. Soution in time and frequency domains. Transfer function.
2. Concentrated parameter models. First order systems; stationary gain and time constant. Second order systems, stationary gain, time constant and damping factor.
3. Linearization of non-linear systems.
4. Time delays.
5. Complex systems. Representation using empirical models.
6. Industrial instrumentations for process control: sensores and transmiters, controllers, final control elements. 
7. Closed loop control (feedback).
8. Dynamic behavior of closed loop control. Stability analysis.
9. Controler tuning; criteria and methods.
10. Feedforward and ration control.
11. Advanced control startegies: cascade control, adaptative control and time delay compensation control.
12. Representation of control systems using P&I diagrams.
13. Digital systems for process monitoring, comand and control. Analog and digital signal treatment.

Teaching methods and learning activities

Teaching will be based on presential classes for presentation and discussion of concepts and study cases. Software tools (Scilab/Xcos) will be used for computer-based learning. Pratical exercises will take place using real PID control systems.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	75,00
Trabalho escrito	25,00
Total:	100,00

Calculation formula of final grade

The final grade, CF, is given by:

CF = 0.25 * CT + 0.75 * CE 
wher CT is the average grade of the reports for the works performed during the semester, and CE is the grade of the axam. The exam will have a part without consultation (40 %) and a part with consultation (60 %).

In order to pass the course, a minimum grade of 8 in the exam is mandatory.

Examinations or Special Assignments

Two work reports:

1) Systems Dynamics 

2) Process Control 

Special assessment (TE, DA, ...)

Final exam.

Classification improvement

Each student may choose between doing the second exam ("recurso") in order to improve only the grade of the first exam, keeping the grade for the work report, ou improve both grades, so that the final grade will be that of the second exam.
