A lateral controller design for an unmanned vehicle

This paper proposes a lateral control system for an unmanned vehicle to improve the responsiveness of the system with a PD control. Heading error can be stabilized and the transient response characteristics can be improved with the controller. In this paper, a mathematical modeling of the vehicle dynamics using two degrees of freedom is used for the controller design. Waypoint tracking method of autonomous navigation was done with the Point to Point algorithm with position and heading measurements from GPS receivers. Performance of the designed controller was verified through experiment with a real vehicle.
