Abstract
Stripper yang terdapat pada PT. Petrochina East Java
mempunyai permasalahan yaitu naiknya ketinggian yang
tidak bisa dikendalikan oleh PID konvensional biasa. Hal ini
terjadi karena naiknya laju aliran yang menuju stripper
terlalu cepat dan tinggi. Perancangan kendali feedback
feedforward dilakukan dengan tujuan untuk memberi solusi
atas permasalahan tersebut. Perancangan pada feedforward
ini dilakukan untuk mengenali seberapa besar laju aliran
yang masuk pada stripper PV 3300 sehingga bisa mengatasi
fluktuasi yang terjadi. Efek dari kendali feedforward ini
memberikan masukan pada elemen akhir sebagai fungsi dari
perubahan laju aliran. Simulasi dilakukan terhadap kendali
feedforward yang telah dirancang dengan dipengaruhi
gangguan laju aliran antara 20 kg/s menuju 70 kg/s. Hasil
yang terbaik adalah dengan Max overshoot=20 %, settling
time (ts)= 22 s, peak time (tp)= 10 s, rise time (tr) = 7 s,
lead per lag= ½, gain feedforward= 0.86. ========== Stripper which in PT. Petrochina East Java has a
problem that increasing level which cannot controlled by
general PID convrntional. It is cause raising flow to stripper
very fastest and highest. Design of feedback feedforward
controller done with purpose to give solution for that
problem. This design of feedforward done to know how fast
the flow that entered to the stripper PV3300 so that can
handled the fluctuation. The effect of feedforward control give
input to the final control elemen as a function delta flow rate.
The simulation done for feedforward controller has been
designed influenced by disturbing flow rate between 20 kg/s
to 70 kg/s. the best result is Max overshoot=20 %, settling
time (ts)= 22 s, peak time (tp)= 10 s, rise time (tr) = 7 s,
lead per lag= ½, gain feedforward= 0.86.
