航空发动机结构参数和非结构参数不确定系统鲁棒H∞输出反馈控制
ROBUST H∞ OUTPUT FEEDBACK CONTROL OF STRUCTURED AND UNSTRUCTURED PARAMETER UNCERTAIN SYSTEM FOR AEROENGINE
-
摘要: 分析了航空发动机混合不确定性系统的鲁棒稳定性和鲁棒性能;引入结构奇异值μ综合法,研究了结构参数和非结构参数混合摄动下的鲁棒H∞输出反馈控制;对航空发动机不确定性系统设计的控制器在双转子涡喷发动机气动热力学非线性模型上。Abstract: The robust stability and robust performance of aeroengine mixed uncertain system are analyzed.By introducing structured singular value μ synthesis method,the robust H∞ output feedback control is investigated under mixed structured and unstructured parameter perturbations.Disturbance rejection and servo tracking performance with the designed controllers for aeroengine uncertainty systems are simulated on a nonlinear model of twin-spool turbojet engine.
