Experimental development and numerical simutation of an electro-hydraulic servo-actuator84

---

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 functioning. The model uses the mass flow ratios in order to obtain a more stable and realistic numerical simulation. It is experimentally studied the behaviour of the servo-actuator with different controllers in the control loop. It is tested one proportional controller and two types of fuzzy controllers. The controllers are implemented in MATLAB/SIMULINK and DATA ACQUISITION TOOLBOX is used for the communication with the data acquisition card. The controllers are tested both experimentally and by numerical simulation. One may say the concordance between the numerical results and the experimental data is quite good.

Key words: servo-valve; experimental development; numerical simulation; electro-hydrauic servo-actuator, experimental results
