The purpose of the work is development of the algorithm for the operation of a system to control alter-nating voltage ensuring minimum changes of a voltage spectral structure. It is necessary for precision electro-technologies such as growing monocrystals in which high frequency constituents in spectrum result in the uneven release of induced power into a melt.
The investigation methods are based on a com-puter simulation of alternating voltage control processes, for the analysis of a spectral structure there is used discrete Fourier transformation. The mathematical support developed for the system of control is realized in a matrix form.
A spectrum nearness criterion based on the idea of the distance between signals is offered. The algorithm of the system work for regulator control ensuring minimum changes in the spectrum whenever necessary to change a load or at voltage changes in the circuit is developed.
The testing of the algorithm offered confirms its working capacity. Its realization requires considerable expenditures for initial data storage that confines a realization sphere of the control system by a type of industrial computers.
