Dalam realisasi sistem yang digunakan di industri, sangat sering dijumpai penggunaan metode kendali Proportional-Integral-Derivatif (PID) karena perancangan yang mudah, sederhana dan efektif. Namun pada beberapa aktuator yang memiliki karakteristik responsif memiliki masalah karena penggunaan PID konvensional dapat menghasilkan set-point kick yang berbahaya untuk aktuator tersebut. Pada tugas akhir ini, dilakukan perancangan dan pengembangan algoritma PID Tipe C (I-PD) untuk mengatasi masalah set-point kick yang direalisasikan pada tiga buah Local Control Unit (LCU) dan merancang algoritma master control menggunakan logika fuzzy pada Remote Terminal Unit (RTU) serta merancang Human Machine Interface (HMI) untuk memberikan perintah dan monitoring sistem melalui Master Terminal Unit (MTU). Keseluruhan sistem dirancang menggunakan prinsip sistem kendali terdistribusi (DCS) agar plant dapat terkendali dan terkoordinasi dari jarak yang jauh. Hasil uji dari sistem ini menunjukkan, pengolahan data pada RTU menggunakan algoritma logika fuzzy dapat memetakan nilai error global menjadi nilai input setpoint pada masing-masing LCU. Nilai setpoint yang diterima LCU menunjukkan hasil yang fluktuatif dan dapat diredam oleh kendali I-PD. Hasil pengujian sistem menghasilkan karakteristik respon rise time 1401 s, overshoot 5,29 %, dan settling time 1401 s. Kata Kunci: DCS, error global, I-PD, logika fuzzy, set-point kick.

In the realization of the systems used in industry, it is very common to find the use of the Proportional-Integral-Derivative (PID) control method because of its easy, simple, and effective design. However, some actuators that have responsive characteristics have problems because the use of conventional PIDs can produce dangerous set-point kicks for the actuators. In this final project, the PID Type C (I-PD) algorithm is designed and developed to solve the set-point kick problem realized in three Local Control Units (LCU) and designed the master control algorithm using fuzzy logic on the Remote Terminal Unit (RTU). as well as designing a Human Machine Interface (HMI) to provide commands and system monitoring through the Master Terminal Unit (MTU). The entire system is designed using the principle of a distributed control system (DCS) so that the plant can be controlled and coordinated from a long distance. The test results of this system show that data processing in the RTU using fuzzy logic algorithms can map the global error value to the input setpoint value in each LCU. The setpoint value received by the LCU shows fluctuating results and can be suppressed by the I-PD control. The results of the system test produce the response characteristics of the rise time of 1401 s, overshoot of 5.29%, and settling time of 1401 s. Keywords: DCS, error global, I-PD, fuzzy logic, set-point kick.
