Mathematical models serve as a basic tool for information gaining about technological objects and processes. Suitable mathematical model, which can be effectively used as a integral part of the process control system, requires not only adequacy to the modeled objects but also adequacy of the computing time to the real time, because one of the main criteria of the optimal model is its time saving....
The contribution deals with the creation of mathematical model and its implementation in MATLAB environment in the form of simulation model, which is proposed mainly for analysis of thermal processes in thermo-insulating food packaging. The mathematical model of heat transfer in food packaging is described in the introduction of this paper. It is basically a thermal tank, where the wall heat capacity...
The paper presents a mathematical model of CFB (Circulating Fluidized-Bed) boiler co-fired with power coal, low-grade coal and biomass. The model based on the mass and energy balance equations. Calculation algorithm uses the method included in the European PN-EN-12952-15 Standard (applicable in Poland) and the German DIN 1942 Standard. Parameters and consumption of fuels burning in the boiler (except...
Process control is one of the principal approaches to increase process quality and performance. Model based control system is based on real time mathematical model, which can be used at individual levels of the process hierarchy in the on line real time control system. The model is used for interpretation, planning, and execution of the tasks through the autonomous controllers. For the outlining tasks,...
