Abstract
Dalam sistem kontrol otomatis, final control element (FCE) berperan penting dalam mengatur aliran fluida secara presisi. Salah satu bentuk pengembangan FCE dilakukan melalui integrasi globe valve dengan stepper motor sebagai aktuator utama. Penelitian ini merancang dan mengimplementasikan sistem control valve berbasis globe valve yang digerakkan oleh stepper motor NEMA17, serta membandingkan dua driver motor DRV8825 dan TMC2209 untuk mengevaluasi performanya. Sistem dilengkapi dengan rotary encoder KY-040 untuk input manual, optical rotary encoder untuk validasi posisi, serta sensor arus INA219 dan sensor temperatur DS18B20 untuk monitoring kondisi driver secara real-time. Pengujian dilakukan dalam beberapa mode penggerakan (full-step, half-step, dan micro-step) dengan pengambilan data arus dan temperatur per detik. Analisis Fast Fourier Transform (FFT) dilakukan pada sinyal arus DRV8825 untuk mengevaluasi kestabilan listriknya. Selain itu, performa control valve dievaluasi dari akurasi posisi, responsivitas aktuator, serta karakteristik aliran fluida dan pressure drop berdasarkan pengujian menggunakan valve tester. Hasil menunjukkan bahwa driver TMC2209 memberikan performa yang lebih stabil dan efisien dibandingkan DRV8825, terutama dalam hal kestabilan arus dan temperatur kerja. Rata-rata error pada aktuasi penuh valve sebesar 1,4% (buka) dan 2% (tutup), dengan deadband sekitar 1%. Karakteristik aliran menunjukkan profil quick-opening sesuai tipe disc globe valve yang digunakan. Dengan hasil ini, sistem control valve yang dirancang terbukti layak untuk aplikasi yang membutuhkan kendali presisi menengah serta dapat dijadikan dasar pengembangan lebih lanjut.

In an automatic control system, the final control element (FCE) plays an important role in precisely regulating fluid flow. Integration of a globe valve with a stepper motor as the main actuator is one form of FCE development. In this study, a globe valve-based kontrol system driven by a NEMA17 stepper motor is compared with two motor drivers, DRV8825 and TMC2209, to evaluate their performance. The system is equipped with a KY-040 rotary encoder for manual input, an optical rotary encoder for position validation, and an INA219 current and DS18B20 temperature sensors for real-time driver condition monitoring. Tests were conducted in several driving modes (full-step, half-step, and micro-step) with current and temperature data collected per second. Fast Fourier Transform (FFT) analysis was performed on the DRV8825 current signal to evaluate its electrical stability. In addition, the performance of the control valve is evaluated based on the positioning accuracy, actuator responsiveness, and fluid flow and pressure drop characteristics based on testing using a valve tester. The results show that the TMC2209 driver provides a more stable and efficient performance than the DRV8825, especially in terms of current stability and working temperature. The average error in full actuation of the valve is 1.4% (open) and 2% (close), with a deadband of approximately 1%. The flow characteristics show a quick-opening profile according to the type of disc globe valve used.
