Abstract
In order to meet the requirements of vibration signal monitoring in aero-engine control system,a processing method of vibration signal based on multi-task and real-time control system is presented.The basic principle and algorithm of FFT are analyzed,and an improved FFT frequency domain analysis algorithm is proposed.Under the limited task resources,the vibration signal processing is divided into several links and realized in multiple control tasks.Finally,the analytical treatment and monitoring of engine rotor's vibration signal are realized.After a great deal of analysis and experimental verification,it is proved that the scheme can meet the current test requirements,and lays the foundation for the further research on the vibration signal of the aero-engine control system.关键词
