Optimal control of thrust for turboprop with engine and propeller integration during takeoff
An engine and propeller integrated control architecture was proposed for turboprop engine rapid response during takeoff.Throttle lever was used to schedule the fuel control loop and pitch control loop for fast system response.A optimal control strategy for thrust was developed at the very beginning of the takeoff in order to maximize thrust according to the property of propeller.Air speed was selected to schedule the maximum effective power to improve thrust response during takeoff.The simulated result showed that the thrust increased by 2.59% in average during takeoff,and the time accelerated to takeoff was less than 2.5 s by the proposed optimal takeoff thrust control strategy and integrated control architecture.The system dynamic response was enhanced effectively by the designed method.
