This paper presents a control solution based on dynamic disturbance decoupling control (DDC) for the implementation of an ultra high speed centrifugal compressor for the air management of fuel cell systems. Unlike other displacement compressors, centrifugal compressor has strong coupling between speed, mass flow and pressure, which gives difficulty for its implementation and limits its operation region. In this paper, a unique dynamic disturbance decoupling control strategy, based on the active disturbance rejection control (ADRC) framework, is developed. The simulation results show that it is a great fit for the highly nonlinear and multivariable centrifugal compression system.
