摘要
本文建立了线性二自由度4WS+DYC数学模型,采用最优控制理论,以4WS+DYC汽车的稳态横摆角速度跟踪2WS汽车的稳态横摆角速度作为控制目标,设计了4WS+DYC最优控制器。基于MATLAB/Simulink平台,进行了纯数字仿真,在提高汽车操纵稳定性方面,仿真结果达到了较为理想的效果。
The paper sets up the 2 DOF linear mathematical model of both 4WS and DYC, and designs the optimization controller based on the strategy of steady yaw - rate of 4WS vehicle with DYC tracking steady yaw - rate of 2WS vehicle. Then the paper uses MATLAB/Simulink to realize numerical simulation. On improving the steering stability,it obtains the better control effects.
