Designing Optimal Actuation and Sensing Systems (FY 94 AASERT)

Abstract

This final technical report contains a summary and highlights on research funded by the AFOSR under grant F49620-94-1-0346, titled 'Designing Optimal Actuation and Sensing Systems (FY94 AASERT). This AASERT grant supported three graduate students to work on the following topic: (1) developing design procedures for model reference adaptive control, (2) designing and building an adaptive vibration absorber, and (3) supporting the Air Force Philips Laboratory by designing optimal active structural acoustic control for new composite rocket fairings. The following results were obtained. We developed a general method for designing an MRAC controller applied to a second order SISO plant. An adaptive self-tuning vibration absorber was designed, built, modeled, and tested. We created a modeling technique for the interior acoustic noise levels of rockets during launch, and tested a simply supported cylinder.
