Experimental development and numerical simutation of an electro-hydraulic ser…

In this paper is developed an electro-hydraulic servo-actuator using the identified parameters of a servo-valve. One follows to obtain a null stationary error and a time response as short as possible. The mathematical model of the servo-actuator is deduced taking account the functional model of the open-centre servo-valve. This model is used for the numerical simulation of the system functionin…
