System Identification Using Virtual Instruments
Jim Dempsey and John Selking
Advisor: Dr. I. S. Ahn
Control Systems engineers are faced with two tasks in designing a stable
system. The first task is to identify the system characteristics, and the
second is to design a compensator to control the system. The second of
these tasks is fairly fundamental given the results of the first. However,
determining the systems' characteristics can be a very long and tedious
process. This project provides, through automated experimentation, the
electrical system characteristics for the control engineer. To perform
this automated testing, a virtual instrument is used. A virtual instrument
incorporates a computer and several computer-controlled bench instruments
on a common bus structure in order to form one integrated test tool. This
type of system can be configured to perform many other automatic tests.
