An Improved Acoustic Model Identifying Method in Propeller Synchrophasing Control

摘要：

　　Propeller synchrophasing control is an effective method to reduce cabin noise level of multiple propeller driven airplanes.An improved acoustic model identifying method using a mixed conjugate gradient method was proposed and validated by experiments.The influence of different data acquisition conditions on the identification accuracy was also studied.It is concluded that the improved method can improve the identification accuracy while reducing the real-time communication requirement between modules.
