Autonomous intelligent cruise control using front and back information for tight vehicle following maneuvers
Zhang, Y.; Kosmatopoulos, Elias B.; Ioannou, Petros A.; Chien, C. C. (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 ...

Centralized, decentralized, and overlapping control designs for a segmented telescope
Li, K.; Kosmatopoulos, E. B.; Ioannou, Petros A.; Boussalis, Helen R. (IEEE, 1999)The accurate control of the segments of large segmented telescopes to achieve the desired shape could open the way for the construction of much larger telescopes with much better capabilities. In this article, we consider ...

Class of unmodeled dynamics in robust adaptive control.
Ioannou, Petros A.; Tsakalis, Kostas S. (Publ by American Automatic Control Council, 1988)The authors use time-domain and frequency-domain bounds to characterize the class of allowable unmodeled dynamics in robust adaptive control. This class is a general one and includes time delays, distributed systems, etc. ...

Collision avoidance analysis for lane changing and merging
Jula, H.; Kosmatopoulos, E. B.; Ioannou, Petros A. (2000)One of the riskiest maneuvers that a driver has to perform in a conventional highway system is to merge into the traffic and/or to perform a lane changing maneuver. Lane changing/merging collisions are responsible for ...
