This paper addresses the problem of Bond Graph modelling of nonlinear bioprocesses. The rules for the design of pseudo Bond Graph models of some prototype bioprocesses — one batch and one continuous process — are obtained using the reaction schemes and the analysis of biochemical phenomena. These rules are applied in order to design the Bond(More)
Stratégia adaptívneho riadenia pre triedu nelineárneho rozvoja bioprocesov This paper presents the control problem of a class of propagation bioprocesses that are carried out in fixed bed reactors. Since the dynamics of these processes are described by partial differential equations, in order to obtain useful models for control purposes, a possible method(More)
This paper presents a specialized device, Slave, part of the monitoring system of local antihail units for rockets launch. This device ensures correct communication between local units and central command unit. The first part sets Slave device position in the monitoring system, and then there it is a detailed description of the hardware parts of the device.(More)
A nonlinear adaptive controller for a class of nonlinear plants with incompletely known and time varying dynamics is presented. It is based on a recurrent neural network used as a dynamical model of the plant. The adaptive controller design is realized by using an input-output feedback linearizing technique. The model parameters, that is the controller(More)
The control of bioprocesses remains an inherently complex problem. Specialist's efforts are directed towards ensuring stability and process efficiency. The necessity to obtain performances without installing a lot of redundant and dedicated expensive equipment, forces the developers to use the techniques available to processing all the information that are(More)
It is well known that in the case of the wastewater treatment bioprocesses, including anaerobic digestion process, usually, the complete knowledge of inputs is not available and therefore the implementation of the control laws becomes a difficult problem. Therefore, in the sequel, for the above mentioned process two observer structures, able to estimate the(More)
