Abstract

This paper presents an investigation of a generalized predictive control technique for online structural vibration suppression under damage condition. The real-time model, used for predictive control design and damage identification, is updated and identified from time-domain input/output data. A method is developed for real-time damage identification, based on the identified prediction matrices. The predicted response error due to the identified damage is integrated into the predictive control design process for the performance of robustness and control under damage. The investigation is demonstrated by application to the Benchmark Active Controls Technology wind-tunnel model. One issue under examination is the performance and stability of the designed controller under various levels of damage.
