System identification of electro-hydraulic actuator servo system

This paper presents the system identification process done on an industrial Electro-Hydraulic Actuator (EHA) system. The model obtained through system identification by aid of System Identification Toolbox of MATLAB and System Identification Toolkit of LabVIEW. Attraction of system identification is ability to obtain system's model with sets of input and output data; without need of prior knowledge on system. The model is later validated with the actual performance of real EHA system.
