This paper presents a design and implementation of Brushless DC (BLDC) motor speed control based on the TMS320F28335 DSP board interfacing to MATLAB/SIMULINK. To obtain the optimal tracking and regulating responses, the PI controller is conducted and designed by pole placement technique. With Back EMF detection, the proposed system is considered as a class of sensorless control. This scheme leads to the speed adjustment of the BLDC motor by PWM. This experiment aims to examine the effectiveness of BLDC motor by testing the BLDC motor of 100 watt. It was found that the speed response of BLDC motor can be regulated at the operating speed of 700 rpm and 1400 rpm at no load and full load conditions.

<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>

AbstractField-circuit model of a brushless DC motor with speed control using PWM method was developed. Waveforms of electrical and mechanical quantities of the designed motor with a high pressure vane pump built in a rotor of the motor were computed. Analysis of electromagnetic phenomena in the system: single phase AC network – converter - BLDC motor was carried out.

Fuzzy Pid Controller

In this project, mathematical model of the Brushless DC motor (BLDC) is developed and the closed-loop Fuzzy PID controller has been simulated in MATLAB-Simulink environment. The three-phase (BLDC) is developed and the DC power is supplied to this machine though six step inverter whose switching state is controlled by the hall signal. The hall effect sensor senses the rotor posit ion of the motor and it generates binary digit number which is decoded and given to the six-step inverter. The mathematical model is developed using the back emf equations and torque equation of the BLDC motor. The PI controller doesn’t operate properly during dynamic state and hence the fuzzy-PID-controller is better option to control and regulate the speed of the BLDC motor which has high performance in comparison to the PI controller. And, we can get the smooth speed-torque characteristics using Fuzzy PID controller.

Brushless DC motor adalah salah satu jenis motor sinkron yang diberi arus DC yang bersumber dari inverter atau power supply. Motor AC menghasilkan arus AC yang dapat menggerakan motor. Pada dasarnya kecepatan motor dapat di atur menggunakan kontroler yang menghitung seberapa besar keluaran yang harus dihasilkan. Pada umumnya input dari kontroler berupa tuas (naik – turun atau putar) dan tombol untuk input awalnya. Oleh Karena itu dilakukan penelitian untuk mengganti input yang mengatur kecepatan motor BLDC. Kontrol kecepatan motor BLDC berbasis logika fuzzy adalah suatu system kontrol yang mengganti input main stream dari kontroler menjadi sensor beban, dan dimana pembacaanya akan dikontrol oleh logika fuzzy untuk mengatur control kecepatan motor BLDC. Penelitian dilakukan dengan dua cara yaitu simulasi dan eksperimen prototype dengan pemberian beban pada sensor yaitu 10 kg, 20 kg, 30 kg, 40 kg dan 50 kg sebagai inputnya. Hasil dari pengujian dan penghitungan yang didapat pada setiap pembebanan menghasilkan kecepatan yang stabil yaitu rata – rata 0.25 detik dengan kecepatan yang hamper setara dengan referensinya. Error pada kecepatan yang dihasilkan antara simulasi dan prototype sangat kecil yaitu kurang dari 1% pada masing – masing pembebanan. Brushless DC motor is one type of synchronous motor that is given a DC current from the inverter or power supply sourced. It produces an AC current that can drive the motor. Basically the motor speed can be set using a controller to compute the result of output. In general, the input from the controller is like a handle (up – down or twist) and a button for initial input. Therefore the research has changed the input that regulates the speed of the BLDC motor. BLDC motor speed is controlled based on fuzzy logic. Fuzzy logic is a control who help load sensor to replace the mainstream input like handle, and where the reader will be directed by logic to determine the speed of the BLDC motor. The research is carried out in two techniques, called simulation and experiment. The prototype is testing with the load on 10 kg, 20 kg, 30 kg, 40 kg and 50 kg as an input. The results of the tests is obtained at each loading resulted in a stable speed which is an average of 0.25 seconds with a speed that is almost the same as the reference. The error signal of the speed is produced between the simulation and prototype is very small, which is less than 1% in each load.
