Abstract :
Applying FFT to identify the amplitude of sine-sweep signals and using variety rate sampling work pattern, an advanced sine-sweep vibration control approach is introduced in this paper. The approach greatly improves amplitude identification accuracy of the sine-sweep signals in the whole frequency range, so that the control system has a good stability and high control capability. Simulation research proves the above results.
