The dynamic response characteristics of modern aircraft vary substantially with ight conditions. These changes require scheduling of the ight control system with variables such as dynamic pressure and Mach number. This scheduling can be accomplished easily for simple controllers but is much more diicult for complex controllers which result from the use of(More)
Stochastic observability refers to the existence of a filter for which the errors of the estimated state mean vector have bounded variance. In this paper, we derive a test to assess the stochastic observability of a Kalman filter implemented for discrete linear time-varying stochastic systems. This test is derived with the assumptions that the system(More)
Acknowledgements " In every conceivable manner, the family is link to our past, bridge to our future. " I want to thank my advisors Professor Gary Balas and Professor Peter Seiler for their guidance and support throughout my graduate career. I am blessed to have the opportunity to work with them. They have acted as the " adaptive controller " of my(More)
