Abstract
Electro-Hydraulic pump-controlled servo systems that have high energy-efficiency can serve as energy-saving system. This paper aims to investigate the servo performance of the electro-hydraulic pump-controlled systems driven by an AC servo motor with variable rotational speed. A constant displacement axial piston pump is used in this research. Thus, the new hydraulic pump-controlled system with an AC motor servo and a constant displacement axial piston pump is investigated for position control of hydraulic servo machines. For that, this paper also develops the control strategy, sign-distance fuzzy sliding mode control, which can simplify the fuzzy rule base through the sliding surface. The developed high response variable rotational speed pump-controlled systems controlled by SD-FSMC are implemented and verified experimentally for positioning control in different stroke and loading conditions. © (2013) Trans Tech Publications, Switzerland.
