The present invention discloses a method for optimizing the preset performance of a gliding high-speed aircraft based on a reaction control system. The method belongs to the field of attitude control of gliding high-speed aircraft. The method is oriented to high-speed aircraft with a reaction control system. An incremental model with equivalent constraints is constructed based on its attitude second-order dynamic system. While ensuring the tracking performance constraints, it reduces the dependence on the accuracy of the aerodynamic model. On the basis of incremental modeling, an event-triggered reaction control system is designed. The event triggering conditions are related to the performance constraints and the control costs, so that compensation is performed at the appropriate time through the reaction control system. Finally, the estimation error, input cost and constraint conditions are simultaneously considered, and an adaptive optimization control of a single evaluation network is constructed based on the adaptive dynamic programming method, thereby achieving optimal control of the gliding attitude of the high-speed aircraft.
