摘要
介绍一种二次调节静液传动车辆和其车速控制原理 ,并根据实际情况建立了整个系统的数学模型。提出一种带修正因子规则的模糊PID控制 ,分别用这种控制器和常规PID控制器对阶跃信号和车辆的 15工况进行仿真分析。结果表明 :采用模糊PID控制具有响应速度快 ,调节时间短等优点 ,更能满足实际车辆的驾驶要求。
The hydrostatic transmission vehicle with secondary regulation and its working principle of speed control are presented,and the mathematic model of the whole system is built.An adaptive fuzzy PID controller with modifying rules is introduced and is compared with ordinary PID controller by simulation on step response and response of 15 operating modes.The results show that adaptive fuzzy PID controller has quicker response and shorter settling time,which better meet the requirements of complicated operation condition of vehicles.
