Abstract: In order to improve the operation quality of the straddle-type monorail vehicle with single-axle bogie, the active control dynamic model of 15 DOF single-axle monorail vehicle was established, taking a single-axle bogie straddle type monorail vehicle as the research object. On this basis, an adaptive network-based fuzzy inference system PID (ANFIS-PID) controller was designed to suppress the lateral and vertical vibration of the vehicle body, and was compared with the original monorail and PID control monorail. The research results show that: compared with the original monorail, the root mean square value of lateral acceleration of PID control monorail and ANFIS-PID control monorail is reduced by 48.37% and 89.06%, the root mean square value of vertical acceleration is reduced by 19.41% and 34.32%, the peak value of lateral acceleration is reduced by 53.00% and 90.30%, and the peak value of vertical acceleration is reduced by 21.72% and 37.60%, respectively. ANFIS-PID control monorail is better than PID control monorail, which can significantly improve the operation quality of monorail vehicles.

摘要： 为提高单轴转向架跨座式单轨车辆的运行品质，以某型单轴转向架跨座式单轨车辆为研究对象，建立了15自由度单轴单轨车辆的主动控制动力学模型。在此基础上，设计了一种自适应神经模糊推理系统PID(ANFIS-PID)控制器，以抑制车体的横向振动和垂向振动，并与原始单轨和PID控制单轨进行了对比。研究结果表明：相比于原始单轨，PID控制单轨和ANFIS-PID控制单轨的横向加速度均方根值分别降低了48.37%和89.06%，垂向加速度均方根值分别降低了19.41%和34.32%；横向加速度峰值分别降低了53.00%和90.30%，垂向加速度峰值分别降低了21.72%和37.60%。ANFIS-PID控制单轨优于PID控制单轨，能显著提高单轨车辆的运行品质。
