✦ Synopsis

Transverse vibration control is an important task in the application of a rotating disk. Here, a novel control solution based on variable structure control with integral compensation (IVSC) principle is formulated, designed and tested, for the control of the transverse vibration of the disk rotating with non-constant angular velocity. The most distinguishing feature of IVSC is its ability to produce very robust control. In many cases, it is insensitive to parametric uncertainty and improves transient response and steady-state error. In this paper, Hamilton's principle is applied to derive the governing equation for the transverse vibration of the disk rotating with non-constant angular velocity. Galerkin's method is employed to discretize the system into infinite modal equations. The approach is based on the independent modal space control (IMSC), and the IVSC is used to design the control procedure to suppress the transverse vibration of the rotating disk in the cases of constant and non-constant speeds.
