| Abstract: | Aiming at the problem of hard fault diagnosis for flight control system,a sensor fault diagnosis system is designed for flight control system by using the Least Squares Support Vector Machines(LS-SVM).The simulation results show that the LS-SVM has high modeling precision and strong generalization.The fault diagnosis based on the LS-SVM can diagnose the sensor's fault and ascertain which sensor goes wrong.Therefore the method mentioned above is valid and advanced. |
