Multichannel Optical Spectrometer as a Measuring Device in Multicriteria Automatic Control Systems

Abstract

A new principle of error signal forming in multicriteria automatic control systems of physical and physicochemical processes is proposed. This principle is based on the contactless optical spectroscopy methods. A characteristic feature of the proposed principle is the forming of a set of error signals based on the results of spectroscopic measurements of radiation emitted as a result flowing these processes. It makes it possible to automatically control several controlled parameters (formed in different parts of the analyzed spectrum), as well as their totality, and quickly change the control criteria. The analysis of error signal forming based on spectral measurement by multichannel optical spectrometer is given. A spectrometer is described as a multidimensional linear system which is characterized in matrix form.
