Considering the actual design of expressway ramp,the moving characters of expressway traffic flow and the requirement of main line speed control,the classical macro and dynamic model of expressway traffic flow is amended in this paper.

And combined with the characteristies of high-volume, high-speed and unstable flow in the intermidiate density (15 veh/km/lane≤p≤Pcrit veh/km/lane), it presents a cooperation control stratege of main line variable speed control (VSC) and on-ramp local integrate feedback control, finally it evaluates the control effects by using computer simulation.

The winder requires constant tension and line velocity control, ADRC which doesn't depend on the exact model of the plant can replace PID controller, with good anti-disturbance, the simulation and experiment result show that ADRC is robust against modeling uncertainty, load changing and noise, and the dynamic performances are improved as well.

This paper introduces steel strip velocity control method at Pushing And Drawing Pickled Steel Strip WISCO.

The control principle and function implement of speed master control,looper height control and head & tail track,and the configuration of control system are described.
