| Abstract | ||||
| The main goal of this paper is to develop and validate the system identification of the Displacement Controlled (DC) linear hydraulic system. The proposed method depends on finding the transfer function that map the simulated output to fit the actual output. To achieve this goal, several experiments have been performed to collect the required data to estimate the parameters including the order of the estimated transfer function. Experimental results in this paper demonstrate that fifth order model with one zero shows good match between the simulated out and the actual outputs. These results demonstrate that the proposed approach can achieve accurate identification of DC linear hydraulic system. Moreover, the proposed approach is general and can be applied to model any hydraulic system working in the linear zone. | ||||
