Abstract

Proyek akhir ini merupakan gagasan teknologi yang berkaitan dengan aplikasi sistem kendali fuzzy berbasis skala model pada sistem pendingin rangkaian sekunder yang terdapat di bengkel dynotest PT. PAL Indonesia (Persero). Gagasan teknologi ini muncul karena sistem yang saat ini digunakan masih belum mampu mengatasi dinamika temperatur yang dihasilkan oleh rangkaian primer. Pengondisian temperatur menggunakan kendali fuzzy karena kemampuannya dalam menentukan keputusan didasarkan pada human reasoning, sehingga diharapkan mampu menggantikan peran operator.
Alur kerja proyek dimulai dengan akusisi data dan penskalaan pada masing – masing komponen rangkaian pendingin sekunder. Perhatian ditujukan pada pompa karena dalam operasinya, melibatkan variasi flow rate, yang mana digunakan sebagai input data dalam melakukan pemodelan kendali fuzzy selain data temperatur. Hasil penskalaan dan pemodelan kendali fuzzy kemudian direalisasi dan diuji coba untuk mengetahui performa sistem.
Hasilnya, diperoleh Skala model ditentukan berdasarkan persamaan – persamaan nirdimensi (dimensionless) yang berlaku pada tiap komponen rangkaian pendingin sekunder. Penskalaan menggunakan angka faktor skala 1:7. Pemodelan sistem kendali logika fuzzy menghasilkan keakuratan desain dengan perbandingan terhadap hasil simulasi menghasilkan tingkat error 0.009%. Hasil uji coba menunjukkan tingkat kestabilan temperatur air yang masuk ke heat exchanger dengan error rata – rata terhadap setpoint (32°C) yaitu 1.8°C. Evaluasi, diberikan pada sistem pendingin skala model, yang mana tidak sepenuhnya hasil penskalaan dari sistem real sesuai.

This final project is technology idea that deals with application of prototype based fuzzy control for secondary circuit cooling in dynotest facility PT.PAL Indonesia. This idea is originated from the problem that concerning in system exist which is unable to carry out dynamics of temperature from primary circuit. Temperature conditioning is controlled using fuzzy logic, because of its reliability to make decision based on human reasoning.
Work flow of this final project is begin with data acquisition from field and scaling each components in secondary circuit cooling. Attention is focused in pump, because of flowrate variation. Then, fuzzy control modelling using Mamdani inference. Finally, prototype making as a realitation of the design and trial to test system performance.
Result after trial obtains prototype is determined based on dimensionless equation from each component in secondary circuit cooling. Dimensions in model scale is obtained using scaling factor 1:7. Fuzzy control system modeling produces design accuracy with comparison to simulation results an error rate of 0.009%. The test results show the level of temperature stability of the water entering the heat exchanger with an average error of 1.8°C to the setpoint (32°C). The evaluation, given to the model scale cooling system, which is not entirely appropriate to real scale.
