Abstract

Deaerator adalah alat yang berfungsi untuk menghilangkan kandungan oksigen pada make up water sebelum masuk ke boiler dan heat exchanger. Deaerator bekerja dengan memanfaatkan kandungan oksigen yang terdapat pada steam untuk pelepasan kandungan oksigen pada make up water. Pengendalian level pada deaerator perlu dilakukan untuk menjaga kestabilan pasokan air ke boiler dan heat exchanger. Perancangan sistem pengendalian dengan metode Internal Model Control bertujuan agar respon pengendali memiliki performansi yang lebih baik daripada pengendalian PID. Dari hasil simulasi didapatkan bahwa pengendali IMC memiliki respon yang lebih baik pada saat uji disturbance dan mampu mencapai set point pada saat uji tracking set point. Parameter tuning IMC menunjukan respon terbaik pada saat λ = 1. Parameter respon pengendali IMC yang didapatkan yaitu settling time = 14,56 s dan IAE = 20,92. ==================================================================================== Deaerator is a tool that serves to eliminate the oxygen content of the make-up water before it enters the boiler and heat exchanger. Deaerator works by utilizing the oxygen content contained in the steam to release oxygen content of the make-up water. Control of the deaerator level necessary to maintain a stable water supply to the boiler and heat exchanger. The design of control systems with the Internal Model Control method aims to control the response has better performance than the PID control. From the simulation results showed that the IMC controller has better response at the time of the disturbance test and is able to achieve set point when the set point tracking test. IMC tuning parameters showed the best response when λ = 1. IMC controller response parameters were obtained, settling time = 14,56 s and IAE = 20,92.
