The major themes in the symposium were compression system instabilities and combustion system instabilities both important limiting factors of gas turbine performance. Results were presented in the area of active control of combustion instabilities demonstrating effectiveness across scales from laboratory rigs to full scale engines and a good understanding of the modeling and control issues. The status of compression systems is somewhat behind this primarily lacking in successful demonstrations on a full-scale engine. The tradeoffs between cost and performance are also less clear in this case. Issues that have been identified for further study include actuation systems, especially the need for high frequency, high reliability actuators, sensing systems capable of operating in high temperature and high vibration environments, and control theory specifically proving robustness and fundamental limits for controllers which are already working in application.
