Control law design of variable cycle engine based on DQN

In order to solve the on-line optimization problem of variable cycle engine, a control law of variable cycle engine based on depth Q network (DQN) is proposed, the minimum fuel consumption of variable cycle engine in cruise phase is achieved by reinforcement learning algorithm. In this paper, the control law of the variable cycle engine in the cruise phase is constructed based on the reinforcement learning algorithm, the pressure ratio can he adjusted online to change the engine working point, so as to reduce the fuel consumption. The unit fuel consumption rate of subsonic cruise can be reduced by 7.45%, and the self-learning time from pulling deviation to fuel consumption can be reduced to the lowest 80s. The performance optimization algorithm can realize the self regulation of engine control law and achieve the lowest fuel consumption with the existence of the engine performance deviation.
