چکیده

Local output feedback stabilization with smooth nonlinear controllers is studied for parameterized nonlinear systems of which the linearized system possesses multiple pairs of imaginary eigen-values, and the bifurcated solution is unstable at the critical value of the parameter. Necessary and suucient conditions are sought for stabilization of such nonlinear bifurcated systems based on the projection method 16] and Lyapunov method 11]. The result was applied to axial ow compressors which are the essential part of jet engines. It is shown that the feedback control law proposed in 13] admits stabilizing property for axial ow compressors at the critical operating point.

Local Robustness of Bifurcation Stabilization with Applications to Jet Engine Control

Local robustness of bifurcation stabilization is studied for parameterized nonlinear systems of which the linearized system possesses either a simple zero eigenvalue or a pair of imaginary eigenvalues and the bifurcated solution is unstable at the critical value of the parameter. It is assumed that the unstable mode corresponding to the critical eigenvalue of the linearized system is not linear...

Output Feedback Control of Jet Engine Stall and Surge Using Pressure Measurements∗

The problem of controlling surge and stall in jet engine compressors is of fundamental importance in preventing damage and lengthening the life of these components. In this paper, we use the MooreGreitzer mathematical model to develop an output feedback controller for these two instabilities (only one of the three states is measurable). This problem is particularly challenging since the system ...

Nonlinear robust disturbance rejection controllers for rotating stall and surge in axial flow compressors

In this paper we develop globally stabilizing robust/disturbance rejection controllers for rotating stall and surge in axial flow compressors with uncertain system dynamics and exogenous disturbances. Specifically, using the nonlinearnonquadratic disturbance rejection optimal control framework for systems with bounded energy (square-integrable) L2 disturbances developed in [15] and the nonlinea...
