Sine simulation of energy regulation based electrohydraulic variable-speed drive

The variable-speed electrohydraulic drive, which can achieve similar energy efficiency as volume drive system, has some good features. But the slow response and poor low-speed performance limit the development of the variable-speed electrohydraulic drive. The energy regulation based variable-speed electrohydraulic drive is a good solution to solve these problems by adding an energy regulation device and a throttling valve into the system. The sine simulations of energy regulation based electrohydraulic variable-speed drive are carried, out. The simulation results have showed that the energy regulation system can not only achieve the goal of a good response, but also keep a good energy-saving performance.
