Comparison of a nonlinear adaptive controller with certainty-equivalence type adaptive controllers
(IEEE, 1995)Recently a new class of adaptive controllers for linear time invariant minimum phase plants has been proposed and analyzed. The design of these controllers is based on nonlinear tools and appears to be different from that ...

Control techniques for a large segmented reflector
(1998)NASA has founded a project to design and construct a test-bed in the Controls and Structures Laboratory at the California State University to study the complex dynamic behavior of large segmented optical systems. The ...

Cruise control with adaptation and wheel torque constraints for improved fuel economy
(2010)Cruise controllers are used to automatically control the speed of motor vehicles. In order to maintain a desired vehicle speed the controller takes over the throttle in a cruise control system which proves particularly ...

Design of strictly positive real systems using constant output feedback
(1999)In this paper, the authors present a linear matrix inequality (LMI) approach to the strictly positive real (SPR) synthesis problem: find an output feedback K such that the closed-loop system T(s) is SPR. The authors establish ...

Directly computable L2 and Lx performance bounds for Morse's dynamic certainty equivalence adaptive controller
(1995)In this paper we consider a model reference adaptive control scheme where the classical error augmentation and standard tuning error normalization are avoided through the use of Morse's high order tuner. We consider the ...
