In this report, lane change maneuver for an automated highway system is investigated as a tracking problem with respect to the virtual desired trajectory (VDT). The two main issues discussed in the report are: 1) design of virtual desired trajectory and 2) design of control algorithms. Four types of desired trajectories are considered. The use of onboard sensors for closed loop control are used. Three closed loop controllers, based on 1) linear quadratic (LC) optimal control, 2) frequency shaped linear quadratic (FSLQ), and 3) sliding mode control are evaluated. Simulation results show that these controllers provide acceptable performance in the presence of uncertainties and disturbances.
