Aiming at the limitation of the traditional RPV dynamic control system,an adaptive fuzzy control strategy of the RPV engine is put forward. We produce an adaptive fuzzy controller which can control wind - gate and oilgate for the working points of the RPV engine in the flight eontrol computer and put it into a two dimension inquired table. After getting present information on the state of the engine by a sensor , we inquire the table by software , at the same time we can get the accurate out - put controlled variable simply by transiting factors. In this way we can achieve the closed - loop control of the engine.
