Instrumented Control Column For Optionally Piloted Aircraft, Andrew J. Klein

Electrical Engineering

Natilus, an aerospace company that is rapid-prototyping optionally piloted aircraft (OPA) for the shipping industry, needs a system that retrieves control column position data in order to manipulate flight simulator parameters in software. At present, a universally compatible system for all aircraft does not exist. Typically, established aerospace companies will sink significant time and money into developing proprietary systems for control column data retrieval as every aircraft is unique in its layout and linkage design. However, as a startup developing their first aircraft, Natilus does not have the privilege of modifying an existing sensor system to work with their HIL …

Stability Analysis Of Systems With Time Delay Simulation Program, Matthew Carroll, Brandon Replogle

Electrical Engineering

A small company wants to develop a CAD tool, ideally as part of the MATLAB suite of tools, for system stability analysis of nonlinear control systems with time-delay. The program must allow the designer to input the system block diagram graphically, then using symbolic expansion, automatically generate the Laplace domain stability boundary and disturbance settling time. The stable regions are then to be graphically plotted as a set of 2- or 3-dimensional parametric stability boundaries. The designer can then input performance constraints on the system through the MATLAB console and a Simulink environment will automatically be generated.
