| 中文摘要 |
| 在自动化高速公路的环境下, 针对一种基于非线性积分器Backstepping方法的交通流密度控制器, 本文提出一种改进的交通流速度控制器设计方法, 选取交通流速度为被控变量, 并采用Backstepping方法进行控制器的设计, 保证使每个路段的交通流速度以指数形式快速收敛到期望值. 与已有的方法相比较, 该控制器极大地提高了算法效率, 而且无需矩阵的逆运算, 可以自动满足系统的可控性条件. 仿真结果显示该控制器可以有效地减少道路拥塞, 有助于在拥堵的高速公路上实现平滑的交通流. |
| 英文摘要 |
| On the basis of the traffic density control design by using the nonlinear integrator-Backstepping method, thismpaper proposes an improved method for designing the traffic flow-speed control by selecting the traffic flow-speed as the controlled variable and applying the Backstepping method to design the controller for an automated highway system. The controller guarantees the traffic flow-speed at each section to be exponentially convergent to the desired speed. Comparing with the prior methods, this controller is superior in algorithm-efficiency, being free from matrix inversion, and automatically satisfying the controllability condition. Simulations show that this controller effectively reduces the congestion and helps to achieve a smooth traffic flow on a congested highway. |
