| 摘 要： | 构建了基于DSP的4WS控制器硬件在环仿真系统,建立了线性二自由度4WS汽车数学模型,以零侧偏角作为控制目标,采用前轮转角比例前馈 横摆角速度比例反馈的控制方法,设计了4WS系统控制器来控制汽车后轮的转角,以TMS320F2812型DSP芯片作为控制器的核心,实现了4WS控制器的硬件在环仿真,得到了较为理想的控制效果。

| Abstract: | The 4WS controller hardware in the loop simulation system based on DSP is designed.Linear 2 DOF mathematical model of 4WS vehicle is set up to control rear wheel turning angle for vehicle using both the front turning angle proportion forward feed and yaw rate proportion feed based on the aim of the sideslip angle for zero.TMS320F2812 DSP is used as electronic control unit to realize 4WS controller hardware in loop simulation,and better control effects are obtained. |
