ABSTRACT
A linear input/output model is identified for a nonlinear distributed
parameter system using a combination of singular-value decomposition
and Karhunen Loeve expansion. The model captures the
dominant behavior of the system around a nominal operating point. A
Quadratic Dynamic Model-Based Controller (QDMC) is designed based on
this input/output model. Sufficient conditions for closed-loop
stability of the infinite dimensional process and finite order
controller are presented and discussed. The system identification
method and a QDMC controller are applied to the multiple-input
multiple-output hydro-dealkylation (HDA) of toluene process in the
presence of common disturbances.
