The application of multi-channel design methods for vibration control of an active structure

摘要: The authors present multi-channel control methods for actively controlling vibration transmission of disturbances in a typical finite beam structure bonded with piezoelectric sensors and actuators. architecture is geared towards disturbance rejection enhanced performance, while maintaining robustness to the active plant variations modeling uncertainties. investigated include linear/non-linear rate feedback control, linear quadratic Gaussian/loop transfer recovery augmented states obtain accommodation, Hinfinity optimization adaptive feedforward based on least-mean-squares algorithm. effectiveness schemes evaluated advantages disadvantages their application are discussed. A hybrid formulation developed account both steady state transient vibrations.
