Abstract
Model Plant Tipe S4 keluaran Yokogawa tahun 1982 ini merupakan
miniatur lengkap pengendalian level, flow, pressure, dan temperature
yang ada di industri. Plant ini terdiri dari dua tangki vertikal. Tangki
pertama (T1) untuk pengendalian temperature dan pressure. Sementara
pada tangki kedua (T2) untuk pengendalian flow dan level. Akan tetapi,
plant tersebut masih menggunakan sistem pengendali analog yaitu sistem
pengendali pneumatik. Oleh karena itu, pada penelitian ini plant
mengalami modifikasi agar dapat dikendalikan menggunakan personal
computer (PC). Dengan perubahan tersebut, plant mampu dikendalikan
menggunakan kontroler digital yaitu PID Prediktif. Pada penelitian ini,
didesain kontroler PID Prediktif untuk mempertahankan level air pada
Tangki 2 meskipun terjadi perubahan parameter plant. Berdasarkan hasil
simulasi, kontroler PID Prediktif dapat mengatasi perubahan beban yang
diberikan serta mampu mempertahankan level sesuai dengan set point.
Hal ini ditunjukan dengan error steady state sebesar 0% pada beban
nominal, minimal, dan maksimal. Sementara itu, pada implementasi,
respon mampu mengikuti perubahan set point yang diberikan dengan
error steady state sebesar 4,568%. Pada saat diberikan gangguan sesaat,
respon mampu kembali pada steady state dalam waktu 90 detik.
Sementara saat diberikan beban, respon mempunyai error steady state
sebesar 3,57% pada beban nominal, 1,242% pada beban maksimal, dan
4,262% pada beban minimal.

Model Plant Tipe S4 Yokogawa is a completely miniature control system
of level, flow, pressure, and temperature in the industry. Model Plant
Type S4 Yologawa is composed of two vertical tanks. The Tank 1 (T1) is
to controlling temperature and pressure. Meanwhile, The Tank 2 (T2) is
to controlling level and flow. However, the plant is stil using analog
controller, such as pneumatic. Therefore, in this final project, plant had
modified. So, Model Plant Tipe S4 Yologawa could be controlled using a
personal computer (PC). With these changes, plant could be controlled
using a digital controller, such as Predictive PID. In this final project,
Predictive PID controlleris designed to maintain water level in the Tank
2. The controller is designed so that water level suitable with set point
even though plant paramater changes. Based on the result of testing,
Predictive PID can handle the given load changes and able to maintain
the level response at set point. Therefore, the level can follow the changes
set point. In simulation, this is indicated by 0 % steady state error at
nominal load, minimal load, and maksimal load. In implementation,
response can follow set point changes with 4,568% error steady state.
Furthermore, when shortly disturbance is given, the response was able to
return to the steady state within 90 s. Meanwhile, when response is given
load, there are 3,57% at nominal load, 1,242% at maximum load, and
4,262% at minimum load.
