Description and Test of the HFFT Resonant Frequency’s Dynamic Characteristics

Article Preview

Abstract:

In this paper, the running stability, the resonant frequency seeking ability of the novel HFFT (High frequency fatigue tester) control system are introduced. Firstly the HFFT control system model is developed. Secondly the HFFT control system dynamic characteristics is simulated and tested, which includes the dynamic load control loop and the frequency locked loop. Finally a experimental result is shown. Compare to the conventional PID control system, the novel tester’s dynamic characteristics are more preferable.
