“…In 1991, Byrnes et al [11] derived the conditions under which a nonlinear system can be rendered passive via smooth state feedback. For surge control of compressors, Gravdahl [13] proposed PBC to stabilize surge and demonstrated that due to certain passivity properties of the model, a simple proportional feedback from mass-flow can stabilize surge oscillations. This method required however the knowledge of the compression system parameters.…”

In this work, we address the stability of compression systems and the active control of surge. Despite considerable efforts to stabilize axial compressors at efficient operating points, preventing surge is still a challenging problem. Here, the twostate Moore-Greitzer model comprising close-coupled valve and including parameter uncertainties and external disturbances, is considered. A feedback linearization approach transforms the original nonlinear model into an equivalent linear system. A passivity-based control is then suggested to robustly stabilize the linearized system in the presence of external disturbances and model uncertainties. Time-domain simulations strongly corroborate analytical developments and demonstrate the robust performance of the controller.

In this work, we address the stability of compression systems and the active control of performance limiting phenomena: surge and rotating stall. Despite considerable efforts to stabilize axial compressors at efficient operating points, preventing and suppressing rotating stall and surge are still challenging problems. Due to certain passivity properties of the widely used Moore and Greitzer model for axial compressors, a robust passivity-based control approach is applied here to tackle the problem. The main advantage of this approach is that robust stabilization and high performance control can be achieved by simple control laws and limited control efforts. Analytical developments and time-domain simulations demonstrate that the developed control laws can effectively damp out rotating stall and surge limit cycles by throttle and close-coupled valve actuations. The robust performance of the controller is validated in the presence of bounded mass flow and pressure disturbances, as well as model uncertainties.
