Abstract: The actuators with which the active control is applied to the surge phenomenon are discussed. The nonlinear equations of the compression system within the actuators are deduced, and the mechanism of additional small perturbation caused by the actuators is explained qualitatively. Then, the dynamically balanced points of the actual actuator are calibrated. Finally,the nonlinear coupled characteristics between the actual actuator and the centrifugal compression system are analysed in detail.

Key words: surg, active controlactuator, compression system
