Abstract:

The optimal control method of aeroengine acceleration process based on GA-SQP hybrid algorithm is proposed. Based on a certain type of aeroengine model, the acceleration process objective function at maximum thrust is
built, respect to the stability and safety indicators as boundary conditions, the GA-SQP hybrid algorithm is used to seek optimum solution during acceleration, several state points within flight envelope are selected for simulations at
maximum thrust mode. Simulation results demonstrate that the acceleration control law can minimize accelerated time at maximum thrust mode, considering both stability and safety of the turbine inlet temperature, the process is perfect.
As a result, the hybrid algorithm is feasible and effective.
