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.

Acceleration Amplitude Control System For Oscillating Silicon Oil Physics Experiment, Eric Chen

Electrical Engineering

This project is an ‘acceleration amplitude control system’ for use in an ‘oscillating silicon oil physics experiment’. The physics experiment has a tray of silicon oil. This tray must oscillate vertically at a specific amplitude (either at or just below the level for Faraday Waves). This control systems manages taking measurements of acceleration amplitude, and also manages correcting the shaker’s driving signal to obtain the correct acceleration. Features of the control system are designed for ease of use, because the system will mostly be operated by professor/ students without background knowledge in electrical engineering.
