(in lingua inglese)
This paper presented a low cost throttle-less hydraulic circuit to control switching loads. The performance of the proposed circuit was tested using a test rig that was constructed using off-the-shelf industrial elements. Results showed that the position steady state error was less than 0.2 mm. Moreover, the cylinder end-effector exhibited good position tracking under a slow tracking signal. The circuit worked 5 times more efficient than a valve controlled circuit to follow the same tracking signal.
