Sliding-mode full-state feedback longitudinal control of vehicles in an automated highway system (AHS)
Longitudinal control of vehicles to maintain some desirable headway between vehicles is one of the most important control issues in advanced vehicle control systems (AVCS) for Automated Highway Systems (AHS). This paper describes the design and simulation results of a nonlinear robust full-state feedback control design based on the sliding mode technique for the automatic maintenance of headway between vehicles. The longitudinal dynamic model of the system is nonlinear, time varying, and has functional and parametric uncertainties. These uncertainties are effectively addressed by the sliding mode controller (SMC). The problem of chattering in sliding mode is eliminated by introducing a boundary layer.
