Prerequisites: Steady state and dynamic material and energy balances; equipment for transport of fluids, for heat exchange, for fluid separation; chemical reactors.
Target skills and knowledge: The students are expected to learn a set of techniques for i) the analysis of the dynamic behavior of chemical process systems, ii) the analysis and design of a process control scheme, and iii) the analysis of PID controller performance. At the end of the course, the student is expected to be able to:
• develop the dynamic model of simple processing units;
• identify which design parameters or operating parameters the dynamic response of a unit depends upon;
• quantitatively characterize the dynamic response of a system to a change in the inputs;
• understand the rationale behind conventional and enhanced control schemes for single processing units and for plantwide systems;
• design feedback and feedforward control schemes for processing units;
• tune a PID controller;
• size a control valve.
Examination methods: The exam includes three mandatory sequential activities: in-course homework activities, final written exam, and final oral exam. Two homework activities are individual, one is to be done in team and completed in 24 hours. The homework activities contribute about 12% of the final grade, the written exam about 44%, whereas the remaining 44% is contributed by the oral exam. The written exam requires solving one or two numerical exercises and/or designing a control scheme in about 2 hours (the use of lecture notes, textbooks and a pocket calculator is permitted). A typical oral exam includes three questions to discuss three topics on the entire course syllabus, and lasts about 45 minutes. The oral exam may be done either in Italian or in English, according to the student’s preference.
Assessment criteria: HOMEWORK AND WRITTEN EXAM
• correctness of the final solution
• clarity and synthesis in the presentation of the results
• appropriateness of use of technical terminology
• rigor of the calculation methodology
• knowledge and understanding of the course contents
• ability to provide quantitative (rather than only qualitative) information on the characteristics of the dynamic response and control system performance of process systems
• ability to discuss the topics in a clear and concise way, and with appropriate use of technical terminology
To encourage study regularity, an increase in the final grade will be granted to those who will take the exam only once, passing it at the end of the course teaching semester.
PROCESS DYNAMICS. Laplace transform; transfer functions; dynamic response of first-order and second-order systems; dynamic response of more complicated systems; effects of poles and zeroes; processes with dead times. Linearization of nonlinear models. Identification of dynamic models from process data.
PROCESS CONTROL. Feedback control for SISO systems: on-off controllers; PID controllers; issues in the practical implementation of PID controllers: reset windup, derivative filters, derivative kick, digital implementation; measurement and control instrumentation; sizing of control valves; dynamic behavior and stability of controlled systems; tuning of PID controllers. Feedforward and ratio control. Enhanced feedback control techniques: cascade control, inferential control, selective control, override control, split-range control, valve position control. Control of MIMO systems: coupling and interaction; relative gains and control loop pairing. Control of distillation columns.
Planned learning activities and teaching methods: Classroom lectures (including short activities in groups), solution of exercises, discussion of case studies, question-and-answer sessions, computer-lab interactive lectures, flipped classes. All class activities are recorded and made available through the Moodle platform. Homework peer assessment is included in the learning activities.
Additional notes about suggested reading: A digital copy of the lecture slides will be made available in the Moodle platform.
