Abstract Developing the intelligent stereo parking lot is an important way to solve the parking problem in cities. According to the movement characteristics of the intelligent stereo parking lot, the speed regulating hydraulic control system of walking, turning and lifting was designed, which could accurately control the speed and position of the stereo parking lot. The speed regulating system was the most important system of the stereo parking lot, so the mathematical model was established. Firstly, the dynamic characteristics of the speed adjustment system were simulated and analyzed by MATLAB/Simulink. Secondly, the experimental prototype was tested and verified. The results show that the circuit design of hydraulic system is reasonable and can meet the accurate control requirement which provides theoretical basis and reference value for further study on the hydraulic control system of intelligent stereo parking lot.

智能立体停车位液压控制系统分析
发展智能立体停车位是解决城市停车难问题的重要途径。由于液压控制系统能够满足对立体停车位的速度和位置控制的精确控制，所以根据智能立体停车位在实际过程中的运动特性，设计出智能立体停车位行走、回转和升降调速液压控制系统。升降调速系统是智能立体停车位最重要的系统，为此建立了升降调速系统的数学模型。首先，基于MATLAB/Simulink对升降调速系统的动态特性进行仿真分析，然后对实验样机的升降调速系统进行测试和验证。测试结果表明，智能立体停车位的液压系统回路设计合理，且满足了对智能立体停车位速度和位置控制精确的要求，为进一步研究智能立体停车位液压控制系统提供理论依据和参考价值。
