Abstract:

A dynamic surface controller is proposed for the control of rotating stall and surge of aeroengine. The new control law is simpler than the Backstepping method which suffers from the problem of “explosion of terms” and the useful nonlinearities which would be cancelled in a feedback linearizing design are retained. With or without measuring rotating stall, the same controller structure could be used and the signal of rotating stall amplitude need not be obtained a priori. The design process based on Lyapunov tools and the simulations show that, by using our scheme, the boundedness of all signals of closed-loop system can be guaranteed.
