摘　　要：主要用模糊控制理论研究横摆角速度反馈控制,设计了横摆角速度反馈控制模糊控制器。研究表明通过横摆角速度反馈控制,汽车的前、后轮侧偏角以及质心侧偏角被限定到一个比较小的范围内,汽车稳定得到显著的改善。说明采用该控制方法可以很好的控制汽车的横摆角速度和质心侧偏角,提高汽车的侧向稳定性。The feedback control of yaw rate is studied based on fuzzy control principle, and the fuzzy controller of feedback of yaw rate is designed. The research indicated that side-slip angle of front and rear wheel and side-slip angle of mass centre are limited within a small range with the feedback control, at the same time vehicle stability is improved significantly. The research results showed that the method of feedback control can enhance the yaw rate and side-slip angle of mass centre, therefore lateral stability of vehicle is further improved.
