The main objective for this course is to provide knowledge in the areas of i) modeling/simulation of dynamic systems, and ii) analysis, design and operation of process control systems. as a complement, it is intended to provide basic knowledge on instrumentation for process control (sensors, controllers and final control elements).
It is expected that after successfully concluding the course, students should be able to:
• Develop mathematical models of dynamic systems.
• Analyze and create block diagrams of linear dynamic systems, identifying the intervening transfer functions.
• Obtain time and frequency responses of linear dynamic systems.
• Identify the main instrumentation used in control of chemical and biological processes, being able to critically analyze their relevance and usage context.
• Design and tune classic controllers according to specified performance criteria.
• Design and tune some advanced control strategies, being able to critically analyze their pertinence.
• Identify the main methods for analog and digital signal processing.

Attendance to classes according to current legislation. Delivery of work reports.
The final grade is based on the following formula:
CF = 0.125 * T1 + 0.125 * T2 + 0.75 * EX
where T1 and T2 are the grades on each work report and EX is the grade on the exam.
The exam will have one part without consultation (50 %) and one part with consultation (50 %).
The criteria to pass the course is: CF >= 9.5 and Ex >= 6.
Two work reports:
1) Systems Dynamics (work disclosed on april 8 and report turned in on april 15)
2) Process Control (work disclosed on may 20 and report turned in on may 27)
Final exam.
Students may choose between doing the second exam (“recurso”) inorder to improve only the grade of the first exam, maintaining the grades for the work reports, or improve both the grades for the exam and the reports, so that the final grade will be the one of the second exam.
