摘要/Abstract

摘要： 采用一种连续型比例积分式的模糊控制器控制涡扇发动机加速过程 ,为了使控制器满足加速过程最大转速、高压涡轮进口最大温度、压气机最低允许喘振裕度等约束条件并改善加速性能 ,利用遗传算法对模糊控制器中的 3个量化因子进行了优化。优化后的模糊控制器完全可以满足加速过程要求 ,具有较好的动态性能 ,适当划分飞行包线后还可扩展到整个飞行包线

Abstract: A continuous PI type fuzzy controller was designed for the accelerating process control of turbofan engine.In order to satisfy the restriction condition of the engine such as the limits of the maximum rotator speed, the maximum temperature of fan turbine and the mimimum stall margin of compressor and improve the character of the engine,genetic algorithm(GA) was used to optimize the parameters of the controller.The results show that optimized controller can meet the engine requirements in the accelerating process.
