Abstract
CONTROL DESIGN FOR BUTOFAN JET ENGINES IS CURRENTLY BASED ONLINEARIZED MODELS VALID AROUND STEADY STATE OPERATING CONDITIONS. THE ENGINE DYNAMICS IS HIGHLY NONLINEAR AND UNDER MANY CONDITIONS SUCH AS STALL THE LINEAR CONTROL DESIGNS AR INADEQUATE. THE OBJECTIVE OF PROPOSED RESEARCH IS TO INVESTIGATE THE APPLICATION OF TWO NONLINEAR CONTROL DESIGN TECHNIQUES WHICH HAVE PROVED SUCCESSFUL IN SOLVING AIRCRAFT NONLINEAR FLIGHT CONTROL PROBLEMS. THE PROPOSAL DISCUSSES THE APPLICABILITY OF THESE METHODS TO TWO OF ENGINE CONTROL PROBLEMS VIZ. UNSTALLED STATE CONTROL AND STALLED STATE CONTROL. PHASE I OF PROPOSED RESEARCH WILL CONSIST OF PROBLEM FORMULATION, MODEL SELECTION AND DEMONSTRATION TO APPLYING ONE OF THE TECHNIQUES TO A CONTROLPROBLEM WITH HIGH POTENTIAL PAYOFF.
