Essay

Dissertation work is devoted to the development of theoretical bases, methods and means of structure-energyforce transformation (SEFT) on the basis of polyelectrodes piezoceramic elements for the control systems. On the basis of analysis of piezoelements properties taking into account the influence of anisotropy and orientation effects of domains in piezoceramics, a method SEFT on the basis of polyelectrodes piezoelements was developed, that takes into account the mutual location of vectors of polarizing, force and field tension between output electrodes. The theoretical bases of SEFT application in polyelectrodes piezoceramic elements in the form of bars, plates and rings were developed. The methods and means of SEFT are developed in piezotransducers with the amplifies of charge, with the combined one-contour and two-contour spatial electromechanical negative feedback with amplifying of volts and/or charge. Application of the developed methods extended the scientific and technical base of planning ofpiezoceramic transformers that allowed the creating of the standards of piezotechnique with descriptions that exceed the best standards of foreign firms-producers in this area.
