| 中文摘要 |
| 入口匝道控制是高速公路控制中的重要内容,但目前在高速公路中使用的入口匝道控制方法的效果均不理想.本文提出使用模糊控制方法进行入口匝道控制的思路,并根据入口匝道控制的原理和模糊控制系统的设计步骤对模糊控制器进行了设计.选用上、下游时间占有率、车速及排队长度等五个模糊量为输入量,根据实际情况分别采用三角形和梯形隶属度函数,建立了包含12条模糊控制规则的规则库,并使用MATLAB工具进行系统仿真.结果表明该控制器用在高速公路入口匝道控制中具有良好的效果. |

| The on_ramp control is an important method in freeway traffic control.But the effects of the current methods of on_ramp control are not satisfactory.The idea of fuzzy control method is promoted in on_ramp control problem.The fuzzy controller was designed based on the theory of on_ramp control and the design process of fuzzy control system.Five fuzzy variables including occupancy,speed and queue are taken as inputs,and triangle and trapezoid subjection degree functions are used according to actual condition.The rule base including 12 rules is established.Finally,the control system is simulated in MATLAB software.The result indicates that the fuzzy controller designed is effective to the on_ramp control. |
