摘要
在汽车下坡的动力学模型的基础上,提出了电涡流缓速器制动力的模糊控制方法。确定了模糊控制规则,设计了电涡流缓速器制动力的模糊控制器,根据汽车的瞬时行驶速度和目标速度差值以及加速度的大小,使电涡流缓速器输出适当的制动力作用在汽车上。利用实际车辆在不同初始运行工况的模拟计算结果表明,设计的模糊控制器控制规则合理,能使汽车在设定的目标速度上稳定行驶,可以应用于工程实践中。
Based on the dynamics model of downhill automobile, the fuzzy control method of eddy-current retarder is put forward. With defined fuzzy control rules, an eddy-current reatarder fuzzy controller is designed, which works to make eddy-current retarder output proper braking force to automobile according to the error between instantaneous velocity and target velocity and acceleration ofthe automobile. The simulation results of an actual vehicle at different initial running situations show the controlling rules of the designed fuzzy controller are reasonable to make the automobile to steadily run at the assumed target velocity, and can be applied into engineering practice.
