Abstract

Abstract:

The smart rotor, a hot research point in the field of helicopter engineering in recent years, has the characteristic of nonlinearity and periodicity and is suited to be researched in the frequency domain. Because of the permissibility of the complicated control algorithm in active vibration control, the neural control method in the frequency domain is suitable for control of a smart rotor. Based on the smart rotor system modeled, the neural control method in the frequency domain for the smart rotor is put forward. The neural emulator in the frequency domain is advanced with the training cases selected by an orthogonal design method. Calculation results show the availability and robustness of the neural control method in the frequency domain.
