The goal of this paper is to study automating the control loop by developing a dual-rate inferential control scheme. ...
Octane quality control at Shell Canada's continuous catalytic reforming (CCR) units is typically done manually due to infrequent measurements of the research octane number (RON). ...

For a dual-rate control system where the output sampling interval is an integer multiple of the control interval, we propose a model-based inferential control scheme which uses a fast-rate model to estimate ...
Comparing such an inferential controller with the corresponding fast single-rate controller, we conclude that the former is no better in disturbance rejection capability; however, in the presence of model-plant ...
We comment that such a dual-rate inferential control scheme has been applied to an industrial continuous catalytic reforming (CCR) unit for octane quality control (Li, Shah, Chen, & Qi, 2001b) , resulting ...
