 Abstract
This paper presents the hacking systems of the servomechanisms that perform the automatic control of the position of a mechanism (platform, steer etc.) depending on the variation of the entrance size that can be of other natures than the mechanic nature.
The entrance size of the mechano-hydraulic of the servomechanism is represented by the command lever, and the exit size is represented by the position of the piston stick or the body of the hydraulic engine.

 Rezumat
În lucrare sunt prezentate modelele sistemelor cu servomecanisme care realizează controlul automat al poziţiei unui mecanism (platformă, cârmă etc) în funcţie de variaţiile unei mărimi de intrare care poate fi şi de altă natură decât mecanică. Mărimea de intrare a servomecanismului mecanohidraulic o reprezintă poziţia levierului de comandă, iar mărimea de ieşire o reprezintă poziţia tijei pistonului sau a corpului motorului hidraulic.
