The developed high response variable rotational speed electro-hydraulic pump-controlled system controlled by SD-FSMC is implemented and verified experimentally for velocity control with various velocity targets and external loading conditions. Furthermore, the energy efficiencies of different experiments are analyzed and compared precisely by the power quality recorder used to measure the electrical power consumed by the AC servo motor. © 2008 Springer-Verlag London Limited. |
