When simple adaptive control (SAC) is applied to vibration systems which include antiresonance modes, there is a problem in that undesirable vibration input is generated. A solution is to use a parallel feedforward compensator (PFC) which makes expansion system consisting of the plant and the PFC into desirable frequency response. On the other hand, the PFC must provide ASPR property to the expansion system. PFC design method based on frequency response fitting is proposed. The matching condition is described using LMI/BMI conditions, and a desirable PFC is obtained by solving an optimization problem described by LMI/BMI conditions. Effectiveness of the proposed method is verified by numerical simulations.
