摘　　要：针对汽车主动转向控制,文章研究了基于横摆角速度和质心侧偏角的综合反馈控制策略。在Matlab/Simulink中建立了整车和主动转向系统的数学模型,在修正变角传动比的基础上设计了基于综合反馈控制的模糊控制器,决策出合理的附加前轮转角,以保证汽车的行驶稳定性,并选取典型工况对控制策略进行了仿真验证。仿真结果表明,基于横摆角速度和质心侧偏角综合反馈控制的汽车稳定性效果要优于单纯的横摆角速度控制。For the active steering control of the vehicle,the integrated feedback control strategy based on the yaw rate and the side slip angle is studied.The mathematic model of vehicle and active steering system is established in Matlab/Simulink.Based on the modified variable steering ratio,a fuzzy controller based on integrated feedback control is intended to make a reasonable additional front wheel angle and guarantee the driving stability of the automobile.To prove the validity of the control strategy,the simulation is conducted under typical conditions.The simulation shows that the integrated feedback control based on the yaw rate and the side slip angle is superior to the simple yaw rate control in the stability of the vehicle.
