Abstract

Brushless Direct Current (BLDC) motors have become a fundamental drive technology in various modern industries, from automotive to aerospace, thanks to their superior efficiency and long operational life. The precision operation of BLDC motors is highly dependent on accurate rotor position information, which is provided by hall sensors. These sensors send signals to a control unit that performs electronic commutation to drive the motor. However, to achieve optimal system response, the implementation of an additional control system is required. This research focuses on the design, implementation, and performance analysis of Proportional Integral (PI) control to regulate the speed of BLDC motors. Based on this target, a proportional control of 0.01990 and an integral gain of 3.29063 are obtained. The simulation results show the system response to a step input with a setpoint of 500 rpm. The motor speed successfully reached 450 rpm in 0.3 seconds, but only stabilized at the setpoint of 500 rpm after reaching 2.5 seconds. The response results also showed ripples in the motor speed, although not significant, caused by non-linear factors inherent in the BLDC motor control system.

Abstract

Agriculture remains a vital sector in ensuring food security, economic stability, and rural livelihoods, particularly in developing countries such as Indonesia. Among various agricultural commodities, red onion (Allium cepa L.) plays a crucial role as one of the most consumed horticultural products and a key income source for farmers. However, its cultivation requires consistent soil moisture, and manual irrigation often results in inefficiency, labor intensity, and inconsistent watering. To address this problem, this study presents the design and implementation of a smartphone-based remote control irrigation robot for red onion cultivation. The system was developed using the ESP32 microcontroller integrated with the Blynk mobile application, enabling wireless control of both mobility and irrigation functions. Hardware components include a DC pump, motor driver, and relay module, supported by a 12-volt rechargeable battery as the power source. The robot’s mechanical frame, constructed from lightweight PVC and acrylic materials, was designed to provide stability and durability in agricultural environments. Performance tests showed that the robot operated reliably within a 20–30 m Wi-Fi range, achieved a movement speed of approximately 3 km/h, and produced water pressure of 160 psi, sufficient for red onion irrigation. Battery endurance reached 1 hour 40 minutes under continuous operation. In conclusion, the developed system demonstrates a practical, low-cost solution that integrates robotics and IoT technology to improve irrigation efficiency, reduce manual labor, and support sustainable water management in red onion farming.
