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。
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.
