| 中文摘要 |
| 结合直接横摆力矩控制和主动前轮转向控制,设计了一种提高制动方向稳定性的复合控制系统.控制器采用2-自由度调节器结构,将前轮转向角视为输入,将作用于车身的外部侧向干扰力视为扰动,通过2-自由度调节器将转向跟随控制和抗扰控制分离,并对制动控制参数进行了优化.文章对有转向输入和路面突变情况下的控制器控制性能进行了仿真研究,并与无方向稳定控制的仿真结果进行了对比.仿真试验证实这种控制方法在提高车辆制动稳定性方面有良好的效果. |
| 英文摘要 |
| A compound controller was proposed to improve braking lateral-stability by integrated control of direct yaw-moment control and active front steer.The controller was designed with two-degrees-of-freedom(2-DOF) structure.Front steer angle and external lateral-force acted on the vehicle were regarded as input and disturbances,respectively.So tracking control for steering and disturbance rejection control were uncoupled by the 2-DOF regulator.Braking parameters of the control system were optimized as well.Control performance with steering input and mutation of road condition were investigated by simulation,and the results were compared with those without control.It was verified that the controller is effective on improving lateral stability of vehicle during brake. |
