摘要：
Compared with valve control systems, variable speed hydraulic systems have the advantage of energy saving. But the application field of variable speed hydraulic systems is limited by the shortcoming of low dynamic characteristics. In view of this shortcoming, an energy regulation device is schemed out to be added on the traditional variable speed hydraulic control system, so a new type of hydraulic control system is formed. The energy regulation device can absorb redundant energy during system deceleration, as well as release energy during system acceleration, so the dynamical response of this system can be increased. A control strategy based on energy regulation is put forward to satisfy this system. The experimental results show that this type of system can improve the dynamic characteristics greatly and cut down the energy cost.
