Autonomous intelligent cruise control using front and back information for tight vehicle following maneuvers
(1999)During manual driving, most human drivers often use information about the speed and position of the preceding and following vehicles in order to adjust the position and speed of their vehicles. The purpose of this paper ...

Robustness of nonlinear control systems with respect to unmodeled dynamics
(1996)In this paper, we examine the global stability properties of nonlinear controllers in the presence of high frequency unmodeled dynamics. We develop necessary and sufficient conditions for a general class of nonlinear control ...

A new linear adaptive controller: Design, analysis and performance
(2000)The certainty equivalence and polynomial approach, widely used for designing adaptive controllers, leads to "simple" adaptive control designs that guarantee stability, asymptotic error convergence, and robustness, but not ...
