航空发动机自适应逆控制研究
Study of Aeroengine Adaptive Inverse Control
-
摘要: 将自适应逆控制方法应用于航空发动机控制系统中,用横向滤波器实现了发动机的建模和逆建模,设计了发动机转速自适应逆控制系统。针对系统存在的稳态误差,提出了带积分环节的发动机自适应逆控制结构,提高了系统的稳态精度。飞行包线内的数字仿真结果表明,自适应逆控制方案精度高、跟踪快、鲁棒性较强。Abstract: The adaptive inverse control system for aeroengines was designed.The aeroengine was modeled using linear adaptive filters. The adaptive inverse control structure with integral control was proposed to reduce the steady-state error.Simulation of the aeroengine speed control system in the whole flight envelope was performed,and excellent tracking performance and robustness were obtained.
