摘要: 针对快速路交通这一类复杂的MIMO非线性系统, 提出了一种新的无模型周期自适应匝道调节方法. 该方法本身是无模型的, 控制输入信息和伪Jacobi参数可在整个周期上逐点利用以前周期获得的I/O数据周期地进行更新. 通过严格的数学分析证明了算法的几何收敛性. 仿真结果也进一步说明了所提出方法的有效性.

Abstract: In this paper, a novel model-free periodic adaptive ramp metering scheme is presented for a freeway traffic system, which can be formulated as a general MIMO nonlinear system. The proposed method is model-free in nature, and the control inputs and the pseudo Jacobi parameters are updated periodically in a pointwise manner over the entire period, by directly using the I/O data obtained in the preceding periods. The geometrical tracking performance is shown with rigorous analysis. The simulation results illustrate the validity of the proposed method.
