Based on structural singular value theory, the robust control model for vibration response is built, and the design method of μ- synthesis controller is presented. The main ideal is as follows: by introducing fictive uncertainty, the robust performance problem of vibration response is transformed into the robust stability problem of the augmented system. It can be solved by D K iteration.
