This thesis presents a simple Real Time Embedded Control System (RTECS) in an
application of Intelligent Structure Monitoring. Research in smart structures, especially the
area of vibration suppression, has warranted the investigation of advanced computing
environments. Real time PC computing power has limited development of high order control
algorithms. The system discussed allows for implementation of l/O intensive algorithms and
provides capability for advanced system development.
In an application of Modal Domain Sensing for Vibration Control, RTECS is compared
to a PC AT based system for overall functionality and speed. Using a model development
procedure, the system is optimized for efficient operation and speed. This includes minimizing the
computational overhead associated with I/O. A comparison shows an order of magnitude I
increase in system speed with larger speed increases discussed. The results provide an avenue
for high order control system design. This leads to more accurate device modeling and a higher
level of system control.
RTECS employs a novel RISC microcontroller capable of 15 MIPs continuous performance
and burst rates of 40 MIPs. Advanced CMOS circuits are integrated on a single printed circuit
board measuring 100 mm by 160 mm and require only 1 Watt of power. An operating system
written in Forth provides the flexibility for high speed operation in short development cycles.
