A basic result from higher order differential inequalities is used to obtain a comparison lemma, useful when higher order trajectory derivatives of Liapunov functions are known. 1. Introduction. Several recent results have focused interest on the question of obtaining stability criteria in terms of higher ordered derivatives of Liapunov functions. Yorke [l](More)
A systematic approach to ground vehicle automation is presented, combining low-level controls, trajectory generation, and closed-loop path correction in an integrated control architecture. Development of robotic vehicles for precision agriculture at USU required the automation of a large motorized vehicle. A planar trajectory connecting command waypoints(More)
