摘　　要：在考虑复杂路况下路面附着系数μ变化的情况下,为提高汽车操纵稳定性,提出了一种自适应的横摆稳定性控制方法。采用该方法,设计了以横摆角速度为控制目标的模糊自适应整定PID参数控制器。该控制器能较好地跟踪其期望值。采用CarSim和Matlab/Simulink构建的联合仿真平台,对变附着系数路面的运行情况进行仿真。仿真结果表明,在不同路况下,所设计的控制器均可提高汽车的操纵稳定性。In order to enhance the handling stability of automotives under complicated road conditions with variation of adhesion coefficient μ, the adaptive control method for stability of automotive yaw is proposed. By adopting this method, the fuzzy adaptive tuning PID parameter controller with angular velocity of yaw as the control object is designed. The controller is well tracking the expected values. The operation condition on the road with variation of adhesion coefficient is simulated on co-simulation platform constructed by using CarSim and Matlab/Simulink. The result of simulation shows that the controller designed can enhance the handling stabihty of automotive under different road conditions.
