Abstract: In order to improve the transient performance of turbofan engine,the nonlinear optimal control principle and realization method for turbofan engine afterburning process is studied.Taking advantage of the improved FSQP algorithm,two nonlinear optimal control methods,which for the entry afterburning process and quit afterburning process,are presented.By using these methods,the problem of optimal control for turbofan engine afterburning process can be solved effectively.The optimal control objective will be achieved with the state of the core engine unchanged.During the control process,each constraint is also always satisfied.Finally,the simulation results indicate these optimal control algorithm’s feasibility and better performance.
