Abstract

Brushless direct current (BLDC) motor speed performance is an essential component that must be considered in the electric vehicle drive system. This research aims to obtain the transfer function from the mathematical modeling of the BLDC motor and optimization of the BLDC motor so that a high transient response is received. The method used in this study is to identify system parameters and then model them using the structure of the autoregressive exogenous (ARX) polynomial model. Meanwhile, to get a high transient response performance, optimization is done with a hybrid intelligent controller. The experimental findings indicate that the optimization process utilizing the bat method yielded the most favorable transient response. The resulting values for the proportional gain (Kp), integral gain (Ki), and derivative gain (Kd) were determined to be 31.2685, 7.7375, and -1.1934, respectively. In the current investigation, the minimum frequency value is 6381934.619. Also determined are the transient response characteristics, which include a rise time of 0.289 seconds, a settling time of 10.9 seconds, an overshoot of 3.4%, and a peak time of 1.04 seconds. Furthermore, the closed-loop system demonstrates stable behavior in terms of stability.

Abstract

Brushless Direct Current (BLDC) motor as an electric vehicle driving motor, its speed control is directly proportional to the voltage applied to its terminals. Therefore the applied average voltage or the average current flowing through the motor will change depending on the duty cycle of the ON and OFF time of the pulses, so the motor speed will change. The purpose of this research is to apply the ARM STM32F4 microcontroller to control the speed of the BLDC motor and obtain the transfer function equation of the BLDC motor. The method used in this study is an ARM STM32F4 microcontroller generating a duty cycle through Pulse Width Modulation (PWM) control which causes changes in the ON and OFF switches of the three-phase inverter. The variable change data is then modeled mathematically in the form of a transfer function using the System Identification Toolbox (SIT) application in Mathlab programming. The results of calculations and tests show that the ARM STM32F4 microcontroller functions well in regulating the rotational speed of the BLDC motor.

Abstract

Prolonged labor is potentially dangerous for the mother and fetus. This can be prevented by stimulating the release of the hormone oxytocin to increase uterine contractions so that prolonged labor does not occur. So a tool is needed to stimulate the hormone oxytocin which is made as comfortable as possible. Apart from helping speed up the process of the first stage of labor, this tool can also stimulate the release of the hormone prolactin to help milk production. This system was designed using the Arduino Uno microcontroller type ESP8266, working to stimulate the nipples through vibration. From the results of this study it was found that the vibrations produced could help stimulate the release of the hormone oxytocin so that the first stage of labor took place 72.40% faster than the old theory of the first stage of labour. Highlights: Prolonged labor risks: Emphasizes the potential danger for both mother and fetus in cases of prolonged labor. Oxytocin stimulation: Highlights the importance of stimulating oxytocin release to prevent prolonged labor and promote uterine contractions. Arduino Uno and nipple vibration: Introduces the specific tool designed using Arduino Uno microcontroller and nipple vibration for oxytocin stimulation during labor. Keywords: prolonged labor, oxytocin stimulation, Arduino Uno, nipple vibration, faster labor
