【摘要】 针对车辆线控转向路感模拟控制受外界扰动大、建模困难等问题,基于线性自抗扰控制(LADRC)技术设计了一种车辆线控转向路感模拟控制算法。建立了线控转向路感控制仿真模型,包括驾驶员模型、线控转向系统模型、两自由度车辆模型、轮胎模型及控制器模型等,在给定道路函数条件下进行了系统仿真验证。结果表明,所设计的线性自抗扰控制器可以实现强鲁棒和高精度的车辆线控转向路感模拟控制。更多还原

【Abstract】 To the problem that road feel simulative control of vehicle steer-by-wire(SBW)system is affected by the external disturbance and difficult on model,a kind of control algorithm for vehicle SBW system is designed based on the linear active disturbance rejection control(LADRC)technique.The road feel control simulation model of SBW system is built,including driver model,SBW system model,two degree of freedom vehicle model,tire model and controller model.The simulated and results under given show that the LADRC controller can implement high precision and strong robust control effects on road feel simnlative control of vehicle SBW systems.更多还原
