Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Features of decision wave equation for tasks of electroelasticity Afonin S.M. Features of decision wave equation and structural-parametric model of piezoengine at longitudinal and transverse piezoconverter are obtained, its transfer functions are bult. Effects of geometric and physical parameters of piezoengine and external load on its static and dynamic characteristics are determined. For calculation of automatic control systems for nanometric movements with piezodrive the transfer functions of piezoengine are obtained.
