| Abstract: | A practice that tests the QDY native electro-hydraulic servovalve by means of three input signals(sinusoidal, pulse,pseudo-random) is introduced, the dynamic mathematical model is determined according to the theory of system identification. Moreover, the performances of three methods of identification are compared and a better researching result is obtained. |
