Nově vybudovaný řídící systém bioreaktorů pro zařízení Bioengineering
Prell, Aleš ; Sobotka, Miroslav ; Kujan, Petr ; Šafář, Hynek ; Holler, Pavel
In cooperation of the automation company Proteco Pardubice the complete replacement of classic analogue control units of next two bioreactors by new, PLC driven local control systems for all monitored and controlled parameters was done. Some measuring devices and actuators were substituted by a new technique too and, moreover, a new central SCADA/HMI (Reliance, Geovap Pardubice) system of the set of bioreactors was introduced and the remaining analogue driven fermentors were integrated into it
Solving special equations for multi-level converter
Kujan, Petr ; Hromčík, M. ; Šebek, M.
This presentation described special polynomial equations for multi-level converter. This converter is electrical device which produces AC voltage from DC sources.
Výpočet determinantu rozměrné matice Sylvesterova typu
Kujan, Petr ; Hromčík, M. ; Šebek, Michael
This work is devoted to computation of large n-D polynomial determinants with a special structure. Applications involve n-D systems theory (e.g. coprimeness test for two n-D polynomials) or the theory of algebraic equations. More specifically, these determinants were exploited by Chiasson recently to solve the practical problem of multilevel converter by a special computational procedure. To tackle the concerned problem it is essential to solve a system of polynomial equations with many unknowns.
Jednoduchá adaptační kontrola napájení fed-batch fermentačních procesů
Prell, Aleš ; Sobotka, Miroslav ; Kujan, Petr ; Páca, J. ; Šafář, Hynek ; Holler, Pavel
Introducing and adapting of automated systems of process control contribute to the technology optimisation both from the yield view and fermentation time saving. The substrate feed is controlled according to the actual catabolic need of microbial culture. The total yield did not increase significantly (1.4%, relative standard deviation 4%), but a positive influence on the fermentation time (minus 12%) was found.
