摘　　要：汽车ESP系统是汽车的一种主动安全装置,近年来仿真技术在汽车ESP系统的研究中得到了广泛的应用。基于模糊控制与PID控制,对ESP提出了自适应模糊PID控制的控制方法。首先以某汽车车型为研究对象,建立了其传递函数模型。然后运用Matlab/Simulink,进行了模糊控制器与PID控制器地设计,建立了仿真模型并进行仿真.结果表明,这种方法可以提高汽车的稳定性。实际工作中,由于路面条件不断变化,并且汽车本身是一个复杂的系统,传统控制方法无法进行有效地控制,自适应模糊PID控制器可以不断地调整参数,进行控制。目前,以完成关于该控制算法的控制器设计。Automobile ESP is a kind of Active safety device.Recently,the simulation was widely used in the research of Automobile ESP.A new method of the self-adaptive fuzzy PID control was put forward for ESP basing on the fuzzy control and PID control. First, a transfer function model of automobile was established, and then designing the fuzzy controller and the PID controller by using Matlab.At last, we use simulink to do the simulation experiment. It turned out that this method can improve the stability of automobile.In practice, because of the change of road conditions,and vehicle is also a complex system, Traditional control methods can not work effectively.Self-adaptive fuzzy pid controlling can constantly control by adjusting parameters. Now, the design of the controller using this control algorithm have been finished.
