【Abstract】 The acceleration features of a turboprop engine were analyzed based on a core engine model,and the regulation analysis was carried out.The combination of a core engine model and fuel-propeller integrated mechanism was established.Fuel-propeller integrated model was built up for further design of proportional integral differential(PID) controller.Based on the integrated model,a close-loop controller engine was designed.A feed-forward section was added to the system for engine power overshoot constraint.Simulation validation was evaluated and verified by comparing the experimental rig’s test data and simulation output data.更多还原
