Abstract

Wave-absorption control with online simulation of an imaginary system is applied to 1-dimensional periodic body-and-spring system and flexible structures, rope and beam, approximating as lumped systems by using the finite difference method. Wave-absorption control with imaginary system, where the controller is installed near fixed boundary, is effective and practical to suppress the vibration, which is not realized by conventional mode-based vibration control method. Experimental results on rope system have shown the effectiveness of the present method.
