Active vibration control of structures incorporating adaptive feedforward control algorithms

摘要

A new adaptive feedforward control scheme is proposed to suppress the vibrations of a high-rise buildign which is subjected to seismic excitation. The control system consists of a robust state feedback controller and an adaptive feedforward controller. Which can efficiently use informations from remote sensors via wireless communication means. A new robust adaptive algorithm with assured stability is presented to improve the output erro bound by using a prior bound of uncertain term. Numerical simulation results indicate effectiveness of the adaptive feedforward control and give an optimal sensor location that can minimize the maximum movement of a mass of dynamic absorber.
