This experimental work concerns the multivariable nonlinear control of a pilotsize continuous polymerization reactor with generically singular characteristic matrix. The control problem is to control conversion and temperature in a continuous stirred tank reactor by manipulating two coordinated flow rates (reactor residence time) and two coordinated heat inputs. A nonlinear controller is synthe...

Many kinetic studies of oxygen delignification have been reported in literature. In the past these studies were mostly performed in batch reactors whereby the caustic and dissolved oxygen concentrations are changing during the reaction. This makes it difficult to determine the reaction order of the different reactants in the rate expressions. Also the lignin content and cellulose degradation of...

A novel approach for stabilizing intermediate steady state of CSTR is proposed by using a special type of periodic forced operation, socalled mediating operation. Mediating operation enables to produce new additional steady states for which one of new intermediate steady states is stable. Thus proposed approach employs a periodic forcing for stabilization of a selected steady state by control o...

This paper describes the text-to-speech system entered by The Centre for Speech Technology Research into the 2016 Blizzard Challenge. This system is a hybrid synthesis system which uses output from a recurrent neural network to drive a unit selection synthesiser. The annual Blizzard Challenge conducts side-byside testing of a number of speech synthesis systems trained on a common set of speech ...

This paper presents the application of robust static output feedback control (RSOFC) to an exothermic continuous-time stirred tank reactor (CSTR) with parametric uncertainties. Necessary and sufficient conditions for stabilization of a linear continuous-time uncertain polytopic system via static output feedback are given at first. Then the problem of RSOFC design is converted to solution of lin...
