73596 - Dynamics And Control Of Chemical Processes M

Learning outcomes

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.

Course contents

FIRST-PRINCIPLES DYNAMIC MODELING OF CHEMICAL PROCESSES.
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.

Teaching methods

Classroom lectures, solution of exercises, discussion of case studies, question-and-answer sessions.

Exercises in the computer room (online classes)

The course takes part in the project for teaching innovation at Unibo

 

Assessment methods

Module 1: Written test using Matlab and oral test. There will be 3 calls (written and oral) in the summer session, 1 in September and 2 in the following winter session. The oral test can also be taken in a subsequent call, but in the same session as the written one.

Module 2: Oral examination

The tests for the two modules can be taken independently.

Teaching tools

Digital copy of the slides presented in class, other material as well as material for the exercises will be made available on virtuale.unibo.it.
