Kertas kerja ini memperkenalkan teknik grafik pengantaramukaan pengguna di dalam pengenalpastian sistem dan penganggaran parameter sistem menggunakan kaedah GPMF yang berdasarkan algorithma IV. GUI yang berdasarkan kepada perisian MATLAB ini mengandungi pra pemproses data, anggaran parameter, penentusah model dan simulasi model. Prosedur penggunaan GUI juga ditunjukkan dalam kajian ini. Proses penentusah model adalah menggunakan proses penentusahan silang. Proses simulasi yang berdasarkan kepada anggaran model matematik telah dilaksanakan untuk menganalisis ciri–ciri dinamik model. Dari keputusan simulasi dan analisis didapati model matematik yang diperolehi adalah boleh dipercayai. Kata kunci: GUI; pengenalpastian sistem; anggaran parameter; GPMF; IV This paper introduces a Graphical User Interface (GUI) application in system identification and parameter estimation of dynamic systems using Generalized Poisson Moment Functionals (GPMF) method based on Instrumental Variable (IV) algorithm. The GUI based on MATLAB consists of data preprocessing, parameter estimation, model validation and model simulation. A step–by–step instruction on how to use the GUI employed in the study is also presented. A validation process had been implemented using cross validation process. Simulation process based on the estimated mathematical model was performed to analyze the dynamic behaviors of the model. From the simulation results and analysis, it could be concluded that the model obtained using this GUI is reliable. Key words: GUI; system identification; parameter estimation; GPMF; IVDownloads
