As n1 less than 85 % , it gives the open - loop control law of fuel and staff , and when n1 more than 85 % , it adopts close - loop to fuel . the paper designed pi controller and adopted reasonable portion for envelopment . 3 . the paper studies transition control process of the engine and gets the main fuel control law of accelerating and decelerating which has been simulated
第二，对其稳态控制过程进行了分析研究，当n1小于85的自始转速时，给出了供油量与油门杆之间的开环控制规律：当n1大于85的自始转速时，采用分块的pi控制方法对燃油进行闭环控制，且对飞行包线进行了合理的划分，用优化方法设计出了pi控制器并用matlab进行了仿真。
