Objective:
Develop autonomous low-authority control systems for structural vibration suppression.
Results:
- A low-authority control algorithm was developed based on the properties of collocated structural control systems.
- The algorithm was applied to the MACE II test article and a in-house flexible structure experiment.
- The results demonstrated the need for 'designing' the open-loop plant to maximize the performance of the autonomous control algorithm based on collocated sensing and actuation.
