Abstract:
Control design for tubofan jet engines is currently based on linearized models valid
around steady state operating conditions. The engine dynamics is highly nonlinear
and under many conditions, such as stall, the linear control designs are inadequate.
Two nonlinear control design techniques which have proved successful in solving
aircraft nonlinear flight control problems have been examined to determine their
applicability to two engine control problems viz. unstalled state control and stalled
state control. Phase I of proposed viz. unstalled state control and stalled state
selection and demonstration to applying one of the techniques to a control problem
with high potential payoff.
