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.AC servo motor; Axial piston pump; Electro-hydraulic pump-controlled system; Hydraulic servo machine; Position control; Signed-distance fuzzy sliding mode control[SDGs]SDG7AC servo motor; Axial piston pump; Electro-hydraulics; Fuzzy sliding mode control; Servo machine; AC generator motors; Energy conservation; Fuzzy systems; Innovation; Loading; Polynomial approximation; Position control; Reciprocating pumps; Sliding mode control; Hydraulic machineryconference paper10.4028/www.scientific.net/AMM.284-287.23152-s2.0-84873891392https://www.scopus.com/inward/record.uri?eid=2-s2.0-84873891392&doi=10.4028%2fwww.scientific.net%2fAMM.284-287.2315&partnerID=40&md5=e8d5db06109abac0c17eb57e86464b7b
