摘　　要：将递阶结构和模糊控制用于高速公路多匝道的协调控制,协调控制器采用多输入-多输出的模糊控制方法协调确定相邻路段的匝道入口调节率;各路段根据协调控制器给定的匝道入口调节率,利用单匝道模糊控制器将系统状态保持在给定的标称点范围内。给出了分层控制系统的结构和控制算法,并在交通仿真软件PARAMICS上进行了仿真实现。仿真结果表明,该方法能够有效地消除交通拥堵,维持主线车流稳定。Hierarchiecal structure and fuzzy control are applied to coordination control of freeway on-ramps. The coordination controller defines the metering rate for every segment of freeway based on multi-input and multi-output fuzzy theory. The state of every segment on the freeway is maintained near the given rate using single ramp control method by direct controller. The hierarchical structure of control system and control algorithm are presented, and simulation are carried out on the traffic simulator PARAMICS. Simulation results show that the control method can effectively smooth traffic jam and maintain the stability of the mainline traffic flow.
