摘　　要：分析了系统主要控制元件——电液比例减压阀的控制特性,建立了电液比例阀控制制动缸系统的非线性数学模型,并运用PID对系统控制特性进行校正,给出了仿真结果.根据所选的比例阀和系统参数进行了联合制动台架试验.结果表明,所选控制策略切实可行,液压缸输出响应较快,稳定性良好,达到了标准要求.The paper first analyses characteristic of the electro-hydraulic proportional control valve-the key control component in the brake system. Then, the system non-line model for the electro-hydraulic control brake cylinder system is established, and the corresponding PID control tactics is put forward to revise the effects on system. According the parameter of the system and material valve characteristic, the brake test was made. The results show the control tactics is feasible, the output response of the cylinder is much rapid and stability. The technical requirements are met.
