In general, the Brushless DC motor speed controller uses an Atmega 16 microcontroller and a MOSFET, which often increases the MOSFET's temperature, especially when the motor is loaded. This article discusses the use of the IC NE555 and CD4017 as a frequency regulator to the MOSFET gate by periodically igniting the forward voltage from the change in the potentiometer value. We carried out the test in an unloaded and unloaded state with voltage variations of 2.5 Vac, 7.5 Vac, 12.5 Vac, and 19.5 Vac. The test results show an excellent tool response where the higher the frequency value, the motor speed will increase. The maximum speed when unloaded reaches rpm at a frequency of 574.6. Whereas in the load test, the full speed reaches 20987 rpm at a frequency of 524.675 Hz. During the test, there was no temperature increase in the MOSFET.

Control Scheme

<p>This paper presents a control scheme for speed control system in brushless dc (BLDC) motor to be utilized for electric motorbike. While conventional motorbikes require engine and fuel, electric motorbikes require DC motor and battery pack in order to be powered up. The limitation with battery pack is that it will need to be recharged after a certain period and distance. As the recharging process is time consuming, a PID controller is designed to maintain the speed of the motor at its optimum state, thus ensuring a longer lasting battery time (until the next charge). The controller is designed to track variations of speed references and stabilizes the output speed accordingly. The simulation results conducted in MATLAB/SIMULINK® shows that the motor, equipped with the PID controller was able to track the reference speed in 7.8x10<sup>-2</sup> milliseconds with no overshoot.  The result shows optimistic possibility that the proposed controller can be used to maintain the speed of the motor at its optimum speed.</p>

Driver Circuit

This low power consumption microcontroller is able to execute instructions with a maximum speed of 16MIPS at a frequency of 16MHz and the ATmega8 is tested to work at a voltage between 4.5 - 5.5 V. Test results of motor drivers 1 and 2 working at a voltage of 4.99 prove that the driver circuit has worked according to its function, namely controlling the motor in 2 directions according to the input given. Motor speed can be controlled by adjusting the motor voltage, the higher the voltage, the faster the motor rotates. The voltage drop will slow down the motor to the desired speed, The sensor response if it encounters an obstacle in front of the wheelchair will stop 10 cm before hitting the object. Then the load test is added gradually from 0 to 451 grams. The wheelchair will appear to be starting to slow down at its maximum weight, making it less responsive to commands. After testing, it can be concluded that the tool works as desired, namely controlling the motion of the wheelchair with voice commands and it can be declared successful although there are still some weaknesses and shortcomings that must be improved.

Aircraft System

Unmanned Aerial Vehicle (UAV) is an unmanned aircraft system that is no longer a special need but has become a general need for the community, and one example is used to capture everyday moments through photos or videos from the air. Among the models of UAV aircraft is the quadcopter, where there is a flight controller that functions to fly the quadcopter by adjusting the speed of each motor. The flight controller that is often used today is the Pixhawk manufacturer. The Pixhawk module is an integrated system that the factory has provided, so it cannot be modified in terms of control and I/O. This research focuses on making an independent flight controller that can be used to fly a quadcopter. The control method that is implanted is Proportional Integral Derivative or commonly known as PID. The flight controller uses the PID control method to adjust each Brushless DC Motor (BLDC) speed to maintain stability while flying. From the test results, the quadcopter can fly stably with KP parameters of 2.5, KI of 0.6, and KD of 1.0. The response time in processing feedback is 3s.

Pumping Unit

In order to drive beam-pumping unit with brushless DC motor (BLDCM), a kind of motor speed regulator was investigated. When pumping unit is in up stroke, BLDCM is power-driven; when in down stoke, pumping unit is braked by BLDCM. To meet the operation mode, PI double closed loops control strategy and Pulse Width Modulation (PWM) are applied. Simulation and test in field show that our design has good control effect and popularizing value.
