Using commercial aviation information systems in operational support airlift decision support systemsKubik, Charles Paul 09 1900 (has links)
Approved for public release; distribution is unlimited / scheduling solutions for routing aircraft, crews and logistical support needed to successfully operate in this new environment. The opportunity exists for the DoD's private aircraft operation, the Joint Operational Support Airlift Center (JOSAC), to utilize some of the same system features used in commercial operations such as NetJets to improve operations. This thesis will analyze the use of commercial air operator strategies and DSS's to be used in JOSAC to improve operational effectiveness. It will look to add new capabilities and processes used in commercial DSS's along with the implementation of the disruptive technology, microjets. Some of the potential benefits include improved operational performance, solutions to scheduling inefficiencies and improved mission readiness. With these improvements the potential for a military microjet operation in the future is a real possibility. / 1st Lieutenant, United States Air Force

Adaptive model reference control of highly maneuverable high performance aircraftCollins, David C. (David Charles), 1969- 17 February 1993 (has links)
This thesis presents an adaptive model reference controller for a highly
maneuverable high performance aircraft, in particular, a modified F18. An adaptive
controller is developed to maneuver an aircraft at a high angle of attack. Thus, the
aircraft is required to fly over a highly nonlinear flight regime. The adaptive controller
presented in this thesis can be viewed as a combination of a linear and a nonlinear
controller. Around a fixed flight condition the adaptive controller converges to a linear
controller; however, the controller remains a nonlinear controller during maneuvers.
The contributions of this thesis lie in two areas. The first area is in control.
A successful application of linear adaptive control is presented for a highly nonlinear
system. A new method is used to generate the reference trajectory. The reference
model uses output feedback to improve the reference trajectory. It is shown that this
improvement is necessary because of the control limitations. This work is also
important to the control of highly maneuverable high performance aircraft. A
successful adaptive controller has been developed to rapidly maneuver an aircraft to
a high angle of attack. The main focus of this thesis is adaptive control. / Graduation date: 1993

Nonlinear control of high performance aircraftBean, Ronnie A. 09 December 1994 (has links)
This thesis presents the design of various controllers for a highly maneuverable,
high performance aircraft, namely the modified F-18. The aircraft
was required to perform high angle-of-attack maneuvers, for which the aircraft
behaves in as a highly nonlinear system. An adaptive PID controller
was used to control the aircraft through these high angle-of-attack maneuvers.
Several nonlinear controllers were then developed based on the adaptive PID
control, and were tested for robustness. This thesis also looks at an improvement
in the aircraft which may improve performance in high angle-of-attack
maneuvers.
The contributions of this thesis are in the areas of control, in general, and
specifically in the area of aircraft control. Successful application of linear
adaptive control and nonlinear control were presented. In the area of aircraft
control, controllers were presented which produce good performance for high
angle-of-attack maneuvers, while maintaining implementability. Also, some
insight is gained into what aircraft changes could improve performance. / Graduation date: 1995
