Based on the uncertainty characteristic of freeway chaos system, the synthetic method was proposed to control the chaos system of freeway by using delay feedback control method and integrator control. The principle is briefly introduced about the system of on-ramp chaos control in freeway with the open-close function. The feedback ramp controller was designed. The goal of chaos control is to realize periodic orbits from unstable periodic movement and the ramp metering is the control variable. The difference effects were discussed in the stimulation experiment among delayed feedback control and ALINEA. The simulation result shows that the principle and the method are correct and feasible.
