| Abstract: | Introducing a practice that tests the QDY electro-hydr aulic servova lve by means of pulse input signal, determining the dynamic mathematical model a ccording to the theory of system identification. Moreover, the performances of i dentification are compared with that of sinusoid's and a better research result is obtained. |
