Abstract

Compressed Air System (CAS) berperan penting dalam menyuplai kebutuhan udara bertekanan untuk proses industri, termasuk mengoperasikan alat pneumatik dan sistem instrumentasi. Bukaan motorized operated valve dengan range sebesar 0 – 100% berfungsi sebagai manipulated variable pada perancangan simulator sistem kontrol compressed air system yang digunakan untuk mengontrol pressure sebagai variabel proses pada range 0 – 87 Psi. Hasil penelitian menunjukan pada mode manual, sistem mampu menampung tekanan hingga 87 Psi (6 bar) dengan bukaan valve diatur dari 10% hingga 100% setiap 180 detik menggunakan kontrol ON OFF. Pemodelan dinamika sistem menggunakan pendekatan FOPDT metode Smith menghasilkan karakteristik integrating process dengan parameter K = 92,718, τ = 711 s, dan L = 197 s, serta validasi model menunjukkan IAE = 6685,6 Psi·s, MAE = 3,78 Psi, dan error model = 4,51%. Serta pengujian tiga tipe pengendali menunjukkan pengendali P memiliki rise time tercepat sebesar 267 detik dengan error steady state 3,19%, pengendali PI lebih akurat dengan error steady-state 2,76% pada rise time 272 detik, sedangkan pengendali PID tidak memadai akibat saturasi manipulated variable dengan %MV maksimum mencapai 531,6%.

The Compressed Air System (CAS) plays a crucial role in supplying compressed air requirements for industrial processes, including operating pneumatic tools and instrumentation systems. The opening of a motorized operated valve with a range of 0–100% functions as the manipulated variable in the design of a compressed air system control simulator used to control pressure as the process variable within a range of 0–87 Psi. The results of the study show that in manual mode, the system is capable of accommodating pressure up to 87 Psi (6 bar) with the valve opening adjusted from 10% to 100% every 180 seconds using ON/OFF control. System dynamics modeling using the FOPDT approach with the Smith method yields an integrating process characteristic with parameters K = 92.718, τ = 711 s, and L = 197 s, while model validation shows an IAE = 6685.6 Psi·s, MAE = 3.78 Psi, and a model error of 4.51%. Furthermore, testing of three types of controllers reveals that the P controller has the fastest rise time of 267 seconds with a steady-state error of 3.19%, the PI controller is more accurate with a steady-state error of 2.76% at a rise time of 272 seconds, while the PID controller proves inadequate due to manipulated variable saturation, with a maximum %MV reaching 531.6%.
