Rahmat, Mohd Fua'ad and Ling, Tiew Gine and Husain, Abdul Rashid and Jusoff, Kamaruzaman (2011) Accuracy comparison of ARX and ANFIS model of an electro-hydraulic actuator system. International Journal on Smart Sensing and Intelligent Systems, 4 (3). pp. 440-453. ISSN 1178-5608


Precise control of electro-hydraulic actuator (EHA) system has been an interesting subject due to its nonlinearities and uncertainties characteristics. Good control can be designed when precise model of the system is available. Linear ARX modelling has widely been applied and satisfying result has been obtained, through linearization process. The objective of this paper is to compare ARX model with nonlinear ANFIS (Adaptive Neuro-Fuzzy Inference System) model, which can represent the real EHA system more precisely using same linearized data. Results show that ANFIS model is more accurate in approximation estimation of EHA system than ARX model on linearized data.
