Abstract

Proses pembuatan munisi melalui beberapa tahap, meliputi pembuatan proyektil, pembuatan selongsong dan perakitan. Pembuatan selongsong diawali dengan membentuk blank menjadi cup dengan proses deep drawing. Langkah tekan silinder hidrolik harus diatur dengan akurat agar cup yang dihasilkan sesuai dengan dimensi yang diinginkan. Sehingga, dibutuhkan sistem kontrol untuk menjamin silinder bergerak sesuai posisi yang diinginkan. Electro-Hydraulic Servo System dengan kontrol PID diterapkan pada penilitian ini. Metode identifikasi sistem digunakan untuk mendapatkan model matematis sistem Model sistem diestimasi menggunakan MATLAB system identification toolbox. Metode identifikasi sistem diawali dengan melakukan uji eksperimen untuk mendapatkan data input – output sistem dengan variasi sampling time 10ms, 20ms dan 50ms. Data yang didapat diolah menggunakan struktur Auto Regressive Exogenous (ARX). Model yang dihasilkan divalidasi dan dipilih berdasarkan kriteria best fits dan residual analysis. Perancangan kontrol PID dilakukan menggunakan metode Ziegler-Nichols, lalu disimulasikan pada software MATLAB – SIMULINK ======================================================================================================== Munitions is made through several steps, including manufacture of projectiles, bullet cartridge manufacture, and assembly. Manufacture of bullet cartridge begins by forming a blank into a cup with a deep drawing process. Punch stroke of hydraulic cylinder has to be accurately controlled so that the resulting cups meet the desired dimensions. Therefore, position control is needed to ensure the cylinder moves to the desired position. Electro-Hydraulic Servo System with PID controller applied in this research. Mathematical model of electrohydraulic servo system is obtained by using system identification method. Model of the system is estimated by using MATLAB System Identification Toolbox. System identification method begins with real time experiment to obtain input – output data with a variety of sampling time 10ms, 20ms and 50ms. The collected data is processed using Auto Regressive Exogenous (ARX). The resulting models are validated and selected based on best fits criteria and residual analysis. Design of PID controller is done by using Ziegler-Nichols method, and then simulated in MATLAB-SIMULINK.
