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.
