This study deals with the hybrid control of response of pressure pulsation of gas in piping excited by a compressor. That is, the response of pressure pulsation of gas in piping is controlled passively by the branch pipe for the tuned mode and actively by a control device installed at the end of the branch pipe for other modes. The mathematical model of the system is formulated and Den Hartog's theory of the optimal dynamic absorber is applied to optimize the parameters of the branch pipe. Next, the state space equation of the system is formulated to determine the optimal feedback gain. Finally, the efficiency of the presented method is verified by the numerical simulation.
