Many infant mortality rates are due to premature events. Premature babies will have difficulty regulating their body temperature. If not treated properly, the baby will suffer hypothermia. To overcome this, you can use a baby incubator as a heater. The baby incubator's temperature is maintained within normal limits of around 33°C–35°C with a relative humidity of 40% RH-60% RH to help stabilize the baby's body temperature. However, in most baby incubators, the system is still controlled manually. So an automatic temperature and humidity control system is needed in the baby incubator. For temperature control, a PID controller is used with a value of Kp = 11,4, Ki = 0,03, and Kd = 1100,1, while humidity control is used with an on-off controller. According to theresults of the PID controller experiments, steady state error was 0,65%, settling time (5%) 5,81 minutes, settling time (2%) 7,75 minutes, and settling time (0,5%) 9,7 minutes. Meanwhile, the results of the humidity experiments with a limit of 58% RH–62% RH, the response obtained was a settling time of 3,4 minutes. Keywords— Premature Babies, Incubator, Ziegler Nichols.

In accordance with technological developments, induction motor control is important in the industrial field. The desired control is to obtain a motor speed response that matches the setpoint. This study uses the specifications of a three-phase induction traction motor, one of which is used in fast trains. Rugged and simple motor construction, high efficiency, easy maintenance, and economy are advantages in the use of three-phase induction motors. The control vector method used is the DTC method with the SVM technique in Simulink Matlab software. This study uses a PI controller with the MO tuning method. The controller parameter values for the speed control loop are Kp = 458.3, Ti = 0.5, and Ki = 916.6. The controller parameter values in the torque control loop are Kp = 1.2, Ti = 0.5, and Ki = 2.4. The controller parameter values in the flux control loop are Kp = 74.9, Ti = 0.49, and Ki = 152.9. This study has simulated and analyzed the response of the PI-Digital controller circuit with the MO tuning method on the DTC three-phase induction traction motor under zero/no load conditions which produces an output response in accordance with specified design specifications, where the output speed is 158.5 rad/s with a settling time of 0.17 seconds and a steady state error of 0.9%. As well as under torque load conditions of 100 N.m, 200 N.m, and 300 N.m, the output generated with the settling time is longer with an additional time of 0.01 second.

In the current development of industrial technology, electricity has been used as the prime mover. One of them is an electric motor, the most widely used is an induction motor. This is because induction motors have advantages in easier maintenance, relatively affordable prices, sturdy construction, and more reliable performance. Examples of the use of induction motors are in modes of transportation, both land, sea and air. However, induction motors still have a weakness which lies in the speed of themotor which is complicated to control. So the speed control research was carried out using the Direct Torque Control (DTC) method. To set the condition of the inverter switching using Space Vector Modulation (SVM). Speed, torque and flux control is carried out with a PI controller, where the PI parameters are determined using the RST-pole placement tuning method. Pole determination is based on the desired design performance criteria. The results of PI parameter on speed, torque, and flux arerespectively Kpω = 1277,59 and Tiω = -0,96, KpT = 8,4 and TiT = -0,2, Kpψ = 67,7 and Tiψ = 0,17. After testing, under no-load condition and a set point of 157 rad/s the system was able to reach a steady state with a steady state error of 0,6% within a settling time of 0,25 seconds. Under conditions of variation in load of 100 Nm, 200 Nm, 300 Nm, the system was able to reach steady state with steady state errors of 0,6%, 0,9%, and 1,2% in settling times of 0,25 seconds, 0,27 seconds, and 0,28 seconds, respectively.

The propulsion system for the fast train in this study uses a three-phase induction motor.The weakness of the induction motor lies in speed control.By using the direct torque control (DTC) method it can be overcome, but this method causes ripples in the output. Therefore, in the DTC method there is an on-of controller which will be set to suppress the ripple value. Setting is done on the value of the on-of switch contained in the flux and torque hysteresis controller to determine the ef ect of varying the hysteresis width on the on-of controller on decreasing ripple. In addition, the execution time is also added to the simulation series in order to determine the ef ect on the DTC method.The result of this study is that the ripple percentage value can be reduced by setting the flux hysteresis controller, which is from 18.238% to 6.330%. Then, with the settings on the torque hysteresis controller can also be reduced, which is from 6.330% to 6.231%. While the addition of execution time on the simulation, the ef ect is directly proportional to the ripple width of the output torque graph.

In this study, an analysis was carried out on the design of the PI controller and feedforward control to reduce the influence of interference due to load torque. Feedforward control works by detecting disturbance or called interference then the magnitude of interference will be compensated by the feedforward controller so that interference is reduced and does not interfere with the output value set by the set point. The determination of Kp and Ki controller parameters is carried out using the optimum symmetrical method and the value of the controller parameters Kp = 11.752 and Ki = 0.42 is obtained.

Indonesia is ranked the fifth country with the world’s most preterm babies. Therefore, the demand for infant incubators remains high. However, most infant incubators today still have some drawbacks, namely, the incubator relies on a grid power source. If a power outage happens, the incubator cannot be used. This research aims to solve the issue by designing a backup system for the incubator integrated with the Internet of Things (IoT) concept. The proposed system consists of an Automatic Transfer Switch (ATS) system, an automatic charging system, and a telemetry unit that can transmit incubator status data to a mobile application via the MQTT protocol. The test result shows that the designed ATS system can switch sources with a delay of 1.085 seconds for the PLN grid – inverter and 0.245 seconds for the inverter – PLN grid. The automatic charging system successfully recharges the Valve Regulated Lead Acid (VRLA) battery using a 3-stage charging method. Furthermore, the designed system can send incubator status data via MQTT protocol to mobile applications with a delivery time of 0.110 seconds. The designed MQTT topology has high scalability proven by the test, that it can connect with up to 1000 clients on one topic.

This study discusses the design of a proportional-integral (PI) controller with a three-phase traction motor as the plant to be controlled. The modulation technique to control the switching on the rectifier uses space vector pulse-width modulation (SVPWM) where the three-phase current and voltage are represented in rotating synchronous coordinates. The control strategy, namely vector control, is used to support the SVPWM modulation technique to provide optimal DC voltage output. Optimal controller design is obtained by tuning the gain parameters of the cascade of speed, flux, and torque controllers using the optimum symmetrical method. The test was carried out by simulating the MATLAB/Simulink software to show the speed stability of a three-phase traction motor. Three-phase traction motor produces an output speed of 158 rad/s, reaches a steady state condition of 0.275 seconds, there is no overshoot, Steady State error is 0.64%.

An incubator functions to provide an environment that resembles the womb for premature babies or infants in need of care. To achieve optimal results, it is crucial for the baby to remain in an incubator with stable conditions. In certain situations, babies often feel uncomfortable and express their discomfort by crying. This discomfort can be addressed by using a swinging motion. By swinging, the baby will feel familiar with the movement since they frequently experienced it while in the womb. This research utilize a fuzzy logic control system with the frequency and intensity/level of the baby's cries as input and a PWM signal that drives the mechanical swing and an LCD indicator as output. The fuzzy logic control employed is the Mamdani method, consisting of fuzzification, rule base, and defuzzification stages.
