An Interim Report of Research on Stochastic and Adaptive Systems (2007)
Athans, Michael, Mitter, Sanjoy K., Valavani, Lena
The research we have conducted over the past several years and in particular during the period February 1, 1980 to January 31, 1981 has been concerned with fundamental aspects of controlling linear...
Rohrs, Charles E., Valavani, Lena, Athans, Michael, Stein, Gunter
In the past few years many model reference adaptive control algorithms have been shown to be globally asymptotically stable. However, there have been no analytical results on the performance of such...

Multivariable Control of a Submersible Using the LQG/LTR Design Methodology, (2002)
Martin,Richard J., Valavani,Lena, Athans,Michael
A multivariable feedback control system is designed for a submersible. The control variables are the bow, rudder, and differential stern control surfaces; these are dynamically coordinated so as to...

Athans,Michael, Mitter,Sanjoy K., Valavani,Lena
This final report describes the research carried out under the AFOSR grant. Research was carried out on the following main topics: (1) realization theory for stochastic systems; (2) linear and...
Robustness of Adaptive Control Algorithms in the Presence of Unmodeled Dynamics, (1998)
Rohrs,Charles E., Valavani,Lena, Athans,Michael, Stein,Gunter
This paper reports the outcome of an exhaustive analytical and numerical investigation of stability and robustness properties of a wide class of adaptive control algorithms in the presence of...
Some Design Guidelines for Discrete-Time Adaptive Controllers, (1998)
Rohrs,Charles E., Athans,Michael, Valavani,Lena, Stein,Gunter
There have been many algorithms proposed for adaptive control which will provide globally asymptotically stable controllers if some stringent conditions on the plant are met. The conditions on the...
