A global optimization based on sequential quadratic programming(SQP) is proposed for aero engine control in dynamic process.Optimization process consists of an overall and a component phase.The authors have implemented algorithm which employs the overall optimal results to redesign relating objective functions.Based on this

component optimization has been carried out with the purpose of correction and the result has been used for cycle control.This approach is applied to aero-engine control under transient conditions.As a result

the process is perfect.The simulation showed that this method can solve the problem that the general local optimization is unfeasible for the system with pure delay part and unmatched model.
