Abstract
A multivariable nonlinear controller is investigated for vibration sup pression of flexible structures. The closed-loop gain matrix consists of a varying term added to a constant term. The varying term is propor tional to the measured signal, providing rapid cancellation of large d eflections and maintaining low noise sensitivity. L2-stability is prov ed, and experimental results show improvement of performance compared to a corresponding linear controller with constant gain.
