摘要

A multivariable nonlinear controller is investigated for vibration suppression of flexible structures. The closed-loop gain matrix consists of a varying term added to a constant term. The varying term is proportional to the measured signal, providing rapid cancellation of large deflections and maintaining low noise sensitivity. L2-stability is proved, and experimental results show improvement of performance compared to a corresponding linear controller with constant gain
