【 摘 要 】

The task of conducting research for dynamics improvement of an electro-hydraulic servo drive by including compensators on FESTO hydraulic learningsystem with low permissible inertial loads on the drive was considered. It has been suggested to simulate large inertial loads, which increase the time constant of the loaded hydraulic cylinder by attaching additional volumes filled with working fluid to the cavities of the executive hydraulic cylinder of the electro-hydraulic servo drive. The efficiency and clarity of the synthesis of compensators for an electro-hydraulic servo drive achieved with the MATLAB/Simulink software environment integration into FESTO hydraulic learningsystem has been shown.
