摘要
Traditional electro-hydraulic servo system with only one proportional directional valve has low control freedom, which makes it unable to adapt to the complex and variable load conditions and causes serious energy waste. To solve this problem, a new multifunctional energy-saving electro-hydraulic servo system is proposed. Firstly, the system structure is introduced and the mathematical model is established. Secondly, a two-level valve controller based on the backstepping control method is designed to guarantee position tracking performance of the system. Meanwhile, a supply pressure controller based on disturbance observer and a supply flow controller based on grey predictor are designed for energy-saving. Finally, the experiment results verify that the proposed system has good position tracking performance and obvious energy saving effect under complex load conditions.
