Abstract

This paper investigates the effects of time-delayed feedbacks on Tuned Mass Dampers (TMD) in the galloping control based on a theoretical model. The Runge-Kutta integration algorithm method is used to solve the model. Then we analyse the effects of the time delay T and the gain strength K of the time-delayed feedbacks on TMD's control effect. With time delay T increasing, the TMD's effect may be either amplified or suppressed, depending on the value of time delay chosen, which is periodic on the parameter T. For a range of values of T and K, the galloping amplitude of the system with TMD and time-delay feedbacks (TTMD) is found to be lower than that of the system with TMD. The TMD with time-delayed feedbacks choosing a suitable time delay T and gain strength K may have better effects on preventing galloping of iced conductors.
