ABSTRAK

Dalam unit Heat Recovery Steam Generator HRSG terdapat suatu unit penghasil uap yang merupakan bahan bakar pokok turbin gas. Unit ini adalah high pressure drum drum bertekanan tinggi yang merupakan penghasil uap bertekanan tinggi. Dua variabel proses yang ada dalam unit ini adalah level air dan tekanan dalam drum dimana kualitas uap yang dihasilkan tergantung dari dua variabel tersebut. Dalam tugas akhir ini dirancang suatu pengendali dengan metode logika fuzzy untuk mendapatkan performansi yang lebih baik. Untuk melihat performansi yang sistem rancangan dilakukan beberapa pengujian meliputi uji step uji tracking set point uji beban uji noise dan uji gabungan. Dari simulasi hasil rancangan dengan uji step untuk pengendalian level diperoleh basil pengendali fuzzy dapat mencapai setpoint dalam waktu 31618 detik dengan maksimum overshoot 0235644dan error steady state 00088420 dan untuk pengendali tekanan pengendali fuzzy dapat mencapai setpoint dengan waktu 339 detik dengan maksimum overshoot 038316 dan error steady state sebesar 0020534 .


ABSTRACT

In Heat Recovery Steam Generator HRSG unit theres a high pressure drum that generate high pressure steam There are two process variable involve in this unit they are level of water and pressure of the drum where the quality of the steam produced depend on those variable. In this final project was design a fuzzy logic control method to reach a better system performance. To know the design system performance some of the test was done include of step test tracking setpoint load test noise test and union test. From this result from step test for level control was obtained that setpoint can reached by fuzzy logic control system at 31618 second with the maximum overshoot 0235644 and eor steady state 00088420 and for pressure control the setpoint can reached by Fuzzy Logic Controller at 339 second with the maximum overshoot 0383168 and eor steady state is 0020534 .
