摘　　要：现有装载机转向控制无法满足对转向偏移距厘米级控制的要求,导致装载机转向偏差较大,需要进行基于脉冲宽度调制(Pulse Width Modulation,PWM)驱动的轮式装载机转向控制的研究。通过高斯投影方法模拟轮式装载机转向路径,建立其转向路径模型,在传统转向控制中融入PWM驱动,并充分考虑滑转率因素,从而助力轮式装载机的转向控制,通过最终判断和控制转矩完成装载机转向后方向的修正。实验结果显示,基于PWM驱动的轮式装载机转向控制转向偏移距均小于0.1m。The existing loader steering control cannot meet the requirements of steering offset cm level,the loader steering deviation is large,and the research on wheel loader steering control based on Pulse Width Modulation(PWM)drive is studied.Simulation of the steering path by Gaussian projection method to establish the steering path model,integrate PWM drive into the traditional steering control to facilitate the steering control of the wheel loader through the final judgment and control torque.The experimental results show that the wheel steering control steering shift distance based on PWM drive is less than O.1m.
