摘要：

The speed control system of variable voltage variable frequency (VVVF) hydraulic elevator with the pressure accumulator has been designed, which is a kind of the innovation energy-saving hydraulic elevator. The control system of the VVVF hydraulic elevator with the pressure accumulator is analyzed, and the speed control of the VVVF hydraulic elevator with the pressure accumulator is studied using the PID control algorithm. The comparison of the experimental researches of energy-saving is carried out for the speed control of the VVVF hydraulic elevator with and without the pressure accumulator. The experimental results show that the VVVF hydraulic elevator with the pressure accumulator has higher efficiency compared with the VVVF hydraulic elevator without the pressure accumulator.
