Iterative Learning Control Based Freeway Ramp Metering with Iteration-varying Parameter
نویسندگان
چکیده
In this work, a revised iterative learning control based ramp metering algorithm with compensation for the iteration-depended traffic free speed is proposed. This control method works well when free speed is iteration-varying, which is the most common situation for the freeway traffic system. With rigorous analysis, the proposed control scheme guarantees the asymptotic convergences along the iteration axis. In order to make the strategy practical, estimation methods of compensation coefficient are proposed as well. Intensive simulations show the effectiveness and superiority of the proposed strategy with iteration-varying free speed, as compared with the pure iterative learning control method.

Iterative learning control based ramp metering tracking various trajectories
In this work, we apply the iterative learning control approach to address the traffic density control via ramp metering in a macroscopic level freeway environment. The traffic density control problem is formulated into an output tracking problem and the tracking trajectories are variable with time and iteration change. Rigorous analyses and intensive simulations show that the iterative learning...
متن کاملAnalysis of an Adaptive Iterative Learning Algorithm for Freeway Ramp Flow Imputation
We present an adaptive iterative learning based flow imputation algorithm, to estimate missing flow profiles in on ramps and off ramps using a freeway traffic flow model. We use the LinkNode Cell transmission model to describe the traffic state evolution in freeways, with on ramp demand profiles and off ramp split ratios (which are derived from flows) as inputs. The model based imputation algor...

In this paper, a fuzzy-neural adaptive iterative learning control (AILC) is proposed for traffic flow systems of a single lane freeway with random bounded off-ramp traffic volumes. It is assumed that the system dynamic functions and input gains are unknown for controller design. An adaptive fuzzy neural network (FNN) controller and an adaptive robust controller are applied to compensate for the...
