“…Yang proposed the component content distribution profile control which can be automatically regulated by dynamically compensating the related extract or scrubbing liquid flow-rate 36 . Lu proposed a model based on generalized prediction of the content of rare earth extracted components to meet the demand of component content floating in a specific interval 37 . A paper applied Static Setting and dynamic compensation based optimal control strategy for the Flow Rate of the Reagent in Ce Pr/Nd Extraction Process 38 .…”

“…The multiple model strategy has been widely studied [26], such as the multiple model control system combined with a predictive controller [27]. For the switching mechanism of the multiple model strategy, the switching state selector is designed based on the fuzzy logic [28], and a Bayes theorem-based switching method is proposed [29].…”

“…The challenges of the multiple model control method are that the smooth switching performance and the practicability to each submodel are difficult to be simultaneously guaranteed. The switching method between operating status has been investigated previously [27][28][29]. However, conventional model switching strategies of the multiple model controller cannot maintain the smooth switching performance because the various matching variables with nonlinear characteristic are hard to be handled with.…”

“…In other words, the designed controller can take an adaptive sampling strategy according to a priori knowledge for different system states. For instance, the aim of rare earth extraction process (REEP) is to obtain several high purity and high yield rare earth products by separating and extracting from mixed rare earth solution [23], [24]. It should be noted that the REEP is generally consisted of the extraction section composed by N stages mixer-settler and the scrubbing section composed by M stages mixer-settler in series.…”
