摘要
分析混沌法下的高速公路主线速度模糊控制的仿真分析情况。通过对称车道元胞自动机仿真分析高速公路主线速度,提出相空间压缩的混沌控制方法。依据混沌与信号控制关系,以高速需求、车辆密度等情况作为条件,遗传算法优化控制模型参数,进行主线速度控制仿真分析。结果显示,混沌控制方法在保证交通安全的情况下,实现车辆的有序通过,降低车辆拥堵率。因此,混沌法下的高速公路主线速度模糊控制,可以提高实际车辆通行能力,具有实际可行性。
The simulation analysis of fuzzy control of highway mainline speed based on chaos method is analyzed.By simulating and analyzing the speed of Expressway main line with cellular automata of symmetrical lane,a chaotic control method of phase space compression is proposed.According to the relationship between chaos and signal control,the model parameters are optimized by genetic algorithm under the condition of high-speed demand and vehicle density,and the main line speed control simulation analysis is carried out.The results show that the chaotic control method can achieve the orderly passing of vehicles and reduce the congestion rate under the condition of ensuring traffic safety.Therefore,the fuzzy control of Expressway main line speed based on chaos method can improve the actual capacity of vehicles,and has practical feasibility.
