摘要：

针对目前立体停车位均采用阀控液压动力系统，存在系统效率低、能耗大等问题，将伺服电机直驱定量泵的节能技术应用于立体停车位的液压系统中.采用滑模变结构算法与模糊控制算法相结合的模糊滑模控制算法作为立体停车位各个工况切换的控制策略，相比于工业中常用的模糊PID控制算法，模糊滑模变结构控制能够对系统设定流量需求进行快速响应，在多个工况切换时，波动小、稳定速度快.同时对使用节能技术的立体停车位运行时的功率、能耗及系统效率进行测试，结果表明使用伺服电机直驱定量泵的液压节能系统与使用传统阀控液压系统相比，能耗降低了31.2%，系统效率提高了33.2%，具有较好的节能效果.

Abstract:

Aiming at solving the serious problems about low efficiency and high energy consumption of current parking tower hydraulic system that adopting valve controlled hydraulic power system, a novel energy saving technology based on constant pump directed by servo motor was used. The fuzzy sliding mode control algorithm which combined sliding mode variable structure algorithm with fuzzy PID algorithm was used as control strategy for parking tower in each working condition. Compared with the regular fuzzy PID algorithm, the fuzzy sliding mode control algorithm had rapid response for the flow demand of the system, and also had small fluctuation and fast stability in the process of switching in multiple operating modes. At the same time, the power, energy consumption and system efficiency of parking tower which had used energy-saving technology mentioned here were tested. Compared with parking tower hydraulic system adopting valve controlled hydraulic power system, energy consumption of the system based on constant pump directed by servo motor was reduced by 31.2% and the system efficiency was increased by 33.2%. The system mentioned here has a better energy saving effect.
Key words: parking tower    energy-saving technology    fuzzy control    sliding mode variable structure    servo drive
