高速公路入口匝道的分散控制
DECENTRALIZED CONTROL AT A FREEWAY ENTRANCE RAMP
-
摘要: 本文基于高速公路时变非线性离散模型,应用反馈控制器参数化方法设计了入口匝道车辆放行的分散控制器,该控制器具有时变非线性的特点.沈大高速公路的系统仿真实验证明了该控制器的有效性.Abstract: Based on a time-variant nonlinear discrete model of freeway,the decentralized controllers at an entrance ramp are designed by using the feedback controllers parametrization method.These controllers are of time-variant and nonlinear.Simulation experiments on Shen-Da Freeway prove the effectiveness of decentralized controllers.
