Dual-loop SISO Controller Development for Food-Extrusion Technology: A Case Study Module

Joel Schlosburg (12 May 2005)

In order to better understand and motivate students to the needs of dynamic modeling and multivariable (MVSISO) design consideration, the case-study of a twin-screw food extruder provides a real-life example with all the requisite components necessary for unit operations management.  The study provides a two-input, two-output system able to be simulated via Simulink model that requires knowledge of RGA and SVD analysis.  It will also require a student to use extensive knowledge of higher-order systems to model certain responses.  All of these needs should create a challenging and engaging system for the students to undertake.
