Model identification and real-time linear position control of servomotor

Plant model identification using experimental data is easy to be obtained with modern tools software such as Matlab and LabView. This powerful software provides reliable and approximate model structure. This paper presents model identification using Matlab System Identification Toolbox from open-loop input-output experimental data that obtained from linear position of a DC servo motor. The effectiveness of the proposed model was tested by a closed loop controller using pole-placement method. Simulation and real time control were conducted to show the reliability of the obtained model. The result shows acceptable performances in both simulation and real time studies.
