Christopher B. McMahan; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| All simulations require some type of user interface to be functional. The problem is that this interface is sometimes written as a tightly coupled part of the simulation itself, buried in the main body of code. This makes the interface very difficult to create, and once created, more difficult to alter. Thus these tightly coupled simulations do not support a simple way to prototype new interface models and incorporate them ... |

| This thesis examines the application of artificial neural networks (NNs) to the problem of dynamic flight control. The specific application is the control of a flying model helicopter. The control interface is provided through a hardware and software test bed called the Fast Adaptive Maneuvering Experiment (FAME). The NN design approach uses two NNs: one trained as an emulator of the plant and the other trained to control the emulator. ... |
