Musiyenko M. Polimorph piezoceramic converters of pressure with a spatial electromechanical negative feedback

The thesis is devoted to perfection polimorph piezoceramic converters with the help of a spatial electromechanical negative feedback. The new method of introduction of a feedback is developed which is entered on the auxiliary channel. It allows to raise accuracy to expand in a some times working strip of frequencies, and also to increase temperature and temporary stability piezoconverters of pressure. Are developed and the block diagrams and gear functions monomorph, bymorph and threemorph piezoconverters with a feedback are investigated. The analytical expressions for account of sensitivity threemorph piezoconverters are received. The results of research are used in Scientific Industrial Complex "Photopribor", in Cherkassy, for special instruments.
