Abstract
The high degree of automation in the use of electronic control in all industrial and mobile applications is most often done by hydraulic proportional control devices, where the regulating element changes remotely in proportion to the electrical signal. This provides the possibility to change the parameters of the hydraulic energy – flow rate and pressure – a realization of adaptive control by proportional electric control. The focus of this study is set on piezoelectric actuators that are electromechanical transducers, suitable for driving and controlling high-speed hydraulic actuators and relatively small insensitive zones. Detailed analysis of various existing designs is performed prior to development of conceptual model. Further, a design exploration is performed through virtual prototypes that helps studying in high level of detail various work parameters. It is of great importance for successive design development as some of the controlled parameters (as deformations) are very sensitive and has great influence over device performance.
