Parametric State Feedback Stabilization Using Block Poles: Application to Centrifugal Gas Compressor Power Plant

摘要

In this paper, the theory of linear multivariable matrix fraction description (MFD) is used for the stabilization of the centrifugal gas compressor system behavior. Where the approximated mathematical model is obtained based on real data measurement of the inputs and output using the parametric system identification. Furthermore to improve the stability of the centrifugal compressor system, a concept of the block poles is used, where the set of right block poles are assigned in the diagonal, controllable and the observable forms in order to obtained the state feedback static matrix gain K, a comparative study is done to select the optimal feedback matrix controller with the best norm and time specifications respectively.
