Abstract

"This thesis details the control of a multivariable chemical process that converts uranium hexafluoride (UF6) to uranium dioxide (UO2). The mathematical model obtained as a result of the identification phase is used as a basis for implementing the Forward Modeling Controller (FMC). The objective behind the implementation of this control scheme was to examine the possibility of using a control strategy that was inherently multivariable in nature as opposed to the existing one where single loop PID controllers are used for each process loop. The ultimate objective was to develop a control strategy that would ensure a better-quality product at a greater throughput by ensuring that the process operated in an optimal region.

System identification, as applied to the process, yielded an accurate dynamic model of the amount of hydrogen fluoride present in the offgas stream. This dynamic model was then used to develop a Forward Modeling Controller. A PI controller was also designed for purposes of comparison. Simulations of the FMC applied to this process showed that this control strategy is superior to the PI controller"-- Abstract, p. iii
