摘　　要：采用神经网络PID控制算法对装载机线控转向系统进行控制,在MATLAB/SIMULINK环境支持下,建立了装载机线控转向系统仿真模型,并通过仿真对比了系统在无校正、常规PID控制与神经网络PID控制的性能,仿真结果显示神经网络PID控制响应时间较快,抗干扰能力强。Steer-by-wire system integrates electro-hydraulic proportion control technology,computer technology and automatic control technology etc,tackles the contradiction between higher working efficiency and the more stability at high speed.The characteristic of Steer-by-wire system is nonlinear,undefined.It is difficult to establish its mathematical model.Because the wheel loader has the distinct characteristics under different operating modes,to choose a suitable control algorithm is the key factor of the perfor...
