Abstract

Steam drum adalah suatu alat yang berfungsi untuk memisahkan antara air dan uap sebelum masuk pada superheater. Steam drum bekerja dengan memanfaatkan air yang masuk pada steam drum melalui economizer, kemudian di panaskan sehingga dapat memisahkan antara air dan uap. Pengendalian level pada steam drum perlu dilakukan untuk menjaga kestabilan pasokan air yang masuk ke steam drum. Perancangan sistem pengendalian dengan metode Internal Model Control (IMC) bertujuan agar respon pengendali memiliki performansi yang lebih baik daripada pengendali PID. Dari hasil simulasi didapatkan bahwa pengendali IMC memiliki respon yang lebih baik pada saat di uji pengendali close loop, dan mampu mencapai set point pada saat uji tracking set point. Parameter tuning IMC menunjukkan respon terbaik pada saat lambda 0,1. Parameter respon pengendali IMC yang di dapatkan yaitu, Maksimum overshoot = 0,00625%, Settling time = 7,545023s, Error steady state = 0,000025 dan Integral absolute error = 8,764348. ===========================================================================================Steam drum is a tool that serves to separate between water and steam before entering the superheater. Steam drum works by utilizing water entering the steam drum through the economizer, then in the heat so as to separate between water and steam. Level control on the steam drum needs to be done to maintain the stability of water supply into steam drum. The design of control system with Internal Model Control method (IMC) aims to controller response has better performance than PID controller. From the simulation results obtained that the IMC controller has a better response at the time of the close loop control test, and able to reach the set point at the time of tracking point set test. IMC tuning parameters show best response at lambda 0.1. IMC controller response parameters that get, that is, Maximum overshoot = 0,00625%, Settling time = 7,545023s, Error steady state = 0,000025 and Integral absolute error = 8,764348
