Abstract

Laju aliran air mengindikasikan volume air yang melewati suatu titik dalam periode waktu tertentu. Laju aliran air pada inlet water tank perlu diatur dengan cermat untuk menjaga keseimbangan level air pada tangki. Dengan menjaga laju aliran air tetap konsisten, level air dalam tangki cenderung stabil seiring waktu. Nilai laju aliran air yang diukur dengan turbine flow sensor bergantung pada pompa yang digunakan. Agar bisa memanipulasi laju aliran air digunakan Variable Speed Drive (VSD). Perancangan sistem kontrol laju aliran air pada plant ini menggunakan PLC sebagai kontroler. Tipe kontrol yang digunakan untuk mengukur laju aliran air menggunakan kontrol PID dengan metode tuning Ziegler Nichols. Telah dilakukan pengujian untuk tipe kontrol P, PI dan PID. Hasil dari pengujian tersebut didapatkan respons dinamik yang paling stabil pada tipe kontrol PID dengan nilai KP 2,3 Ti 3 dan Ti 0.75. Hasil karakteristik dinamik dari tuning PID didapatkan nilai rise time senilai 79 s dan settling time 101 s dengan error steady state 0,02%. Pada tuning ini tidak terdapat nilai overshoot yang mengindikasikan sistem berjalan dengan optimal.

Water flow rate indicates the volume of water passing through a point over a specific period. The water flow rate at the inlet water tank needs to be carefully regulated to maintain the balance of the water level in the tank. By keeping the water flow rate consistent, the water level in the tank tends to remain stable over time. The flow rate values measured with a turbine flow sensor depend on the pump used. To manipulate the water flow rate, a Variable Speed Drive (VSD) is employed. The design of the flow rate control system for this plant uses a PLC as the controller. The control type used to measure the water flow rate is a PID control with Ziegler-Nichols tuning method. Testing has been conducted for P, PI, and PID control types. The testing results showed the most stable dynamic response with PID control type with KP 2.3, Ti 3, and Td 0.75 values. The dynamic characteristics from PID tuning yielded a rise time of 79 seconds and a settling time of 101 seconds, with a steady-state error of 0.02%. This tuning showed no overshoot, indicating that the system operates optimally.
