Abstract

Sistem kendali aliran air merupakan aspek penting dalam berbagai industri, seperti pengolahan air, manufaktur, dan sistem pendinginan. Ketidakstabilan aliran air akibat perubahan beban atau gangguan eksternal dapat menyebabkan ketidakefisienan proses. Penelitian ini bertujuan merancang dan mengimplementasikan sistem kendali PID (Proportional-Intergal-Derivative) berbasis PLC (Programmable-Logic-Controller) dan HMI (Human-Machine-Interface) pada mini plant water flow untuk menjaga kestabilan debit air terhadap perubahan beban. PLC Mitsubishi FX3U-14MR digunakan sebagai pengendali utama yang menerima data dari sensor aliran dan mengatur kinerja pompa air melalui pemrosesan sinyal PID. HMI digunakan untuk memantau dan mengatur parameter kendali secara real-time. Metode tuning yang digunakan adalah Ziegler-Nichols 1. Hasil menunjukan bahwa metode ini mampu mengatur aliran air pada setpoint 5 LPM dengan performa: Overshoot = 0%, Error Steady-State = 1,2%, Rise Time = 15 detik, dan Settling Time = 27 detik. Metode Ziegler-Nichols 1 memberikan respons yang stabil, meskipun memerlukan waktu tuning lebih lama. Sistem ini efektif untuk pengendalian aliran air skala kecil dan sebagai media pembelajaran otomasi industri.

Abstract

The need for a stable and efficient power supply system is crucial in various modern electronic applications to step up and step down DC voltages. One solution is a non-inverting buck-boost DC-DC converter that is capable of stepping up or stepping down the voltage without reversing the output polarity. However, the stability of the output voltage remains a challenge, especially when there is a change in load or reference value (setpoint). This study aims to design and implement a non-inverting buck-boost converter with a Proportional-Integral (PI) controller to maintain output voltage stability. The method used is PI control determined by Ziegler-Nichols Type I to find the proportional constant (Kp) and integral constant (Ki), which is then refined through a trial and error approach, digital PI control is implemented through a program on a microcontroller. The design is tested through simulations using PSIM software and hardware realization based on an Arduino Uno microcontroller with digital-based PI control using a program. The test results show that the system is able to maintain an output voltage of 30V from a 15V input with a settling time of 0.1 seconds in simulation and approximately 0.5 seconds in experimental testing. Despite a maximum overshoot of 22.93%, the system is still able to respond quickly to changes and maintain stability against load variations. These results indicate that PI control is effective in improving the output voltage stability of the non-inverting buck-boost converter, although refinement of the control parameters is still needed to improve the system's precision.
