—This paper describes an improved design procedure for the weighting matrices of the mixed sensitivity problem. Using low-order models, as usual in industrial processes, and based on recent works, the new design will allow to significantly reduce the time response overshoots, without degrading the speed of these responses. Weighting matrices are designed in… (More)
In Argentina, susceptibility of the sunflower crop to Sclerotinia sclerotiorum capitulum attacks can cause significant yield losses. We reported earlier two hybrids among a series obtained from crosses between inbred lines following a factorial mating design that had a sufficient level of resistance to be adapted to the main Argentina sunflower growing… (More)
This paper describes the design of a multivariable robust controller for a drying process. The plant consists of a co-current rotary dryer to evaporate moisture from a waste product. A methodology to design a multivariable QFT controller and pre-filter is shown. The performance obtained with this control strategy has been validated under simulation.
