Abstract
In motion control applications, electro-hydraulic actuators system (EHAs) must be controlled to evaluate the motion of a position rod. A mathematical model is a system description that is based on equations. There are different phases technique which is physical modeling and system identification. Physical modelling have been used Simscape Fluids™ which known as EHA model in this thesis. The attraction of system identification is the ability to obtain a system's model from a set of input and output data without prior knowledge of the system. The objective of this study was to obtain transfer function and identify mathematical model of electro-hydraulic actuator (EHA) system using system identification technique by estimating Simscape Fluids™ model using System Identification Toolbox in MATLAB. The actual performance of the EHA model is subsequently validated to obtained the estimate model. The selected ARX(Auto-Regressive Exogenous) model with the help of the MATLAB System Identification Toolbox. The estimation model known as arxqs model has a best fitting accuracy of more than 90 %. The compare output response of the estimated model is close to the EHA model of the best fitting 93.87 % of electro-hydraulic actuator (EHA) model. The arxqs model has been chosen or selected is fourth-order autoregressive (ARX) model using the arx algorithm because the estimation was achieved.
