Then, a control model of any number of RIDTMD devices for damping the multi-degree-of-freedom structure is established. Taking the H2-norm of the control system as the optimization objective, the RIDTMD device parameters Finally, a three-layer frame structure is taken as an example to analyze the influence of the damping effect and the device parameters of the RIDTMD device on the structural response. Compared with the traditional TMD device, the effectiveness of the damping of the RIDTMD device is verified .
