Performance Seeking Control of Variable Cycle Engine Based on SQP

The research purpose of performance seeking control is to fully unlock the potential of the engine and improve the performance of the engine under the premise of ensuring the stable operation of the engine. In this paper, the performance optimization problem of variable cycle engine can be summarized as an optimization problem with nonlinear constraints. The performance optimization of the maximum thrust mode, the minimum specific fuel consumption rate mode and the minimum turbine inlet temperature mode under the condition of engine component degradation is carried out by using the sequential quadratic programming algorithm.
