CRONE control application for a toll plaza

In this paper a non-integer robust control approach to determine the speed variation downstream to a toll plaza is proposed where the total flow exiting from the toll booths exceeds the capacity of the downstream highway. This can lead to congestion and reduced efficiency due to capacity drop. The proposed control approach is based on non-integer robust methodology. This control strategy assures the robust performances for the traffic velocity and maintains the density on the high ways under a constraint value with the main aim to assure fluid traffic flow. The traffic flow phenomenon is very complex and the main problem stay to avoid the traffic jams on the roads. Hence the purpose of this article is to apply non-integer control algorithm in the toll plaza for maintain the downstream traffic flow density under a constraint density and to assure fluid process. The interest stay to apply a control algorithm containing internal model with Smith structure for predict and reduce the time delay. More over we look to assure robust performances using the non-integer algorithm.
