Methodological questions of intellectual multisensor analyzers construction

In this paper we consider actual questions, connected with construction and usage of multisensor analyzers of "electronic nose" or "electronic tongue" types. Despite a large amount of papers concerning various aspects of this theme, there is a significant lack of methodological works among them. This work presents a discussion on general key problems of improvement of intellectual multisensor analyzers, namely the problems of optimization of sensor system, selection of algorithm means, evaluation of identification ability of the analyzer, typification of the utilized project design solutions at its construction. Typical examples of intellectual multisensor analyzers are presented, which are successfully used in various areas, including that for control and monitoring of water quality. (paper)
