An FPGA-Based Novel Digital PWM Control Scheme for BLDC Motor Drives
Development of advanced motor drives has yielded increases in efficiency and reliability. Residential and commercial appliances such as refrigerators and air conditioning systems use conventional motor drive technology. The machines found in these applications are characterized by low efficiency and high maintenance. A brushless dc (BLDC) motor drive is characterized by higher efficiency, lower maintenance, and higher cost. In a market driven by profit margins, the appliance industry is reluctant to replace the conventional motor drives with the advanced motor drives (BLDC) due to their higher cost. Therefore, it is necessary to have a low-cost but effective BLDC motor controller. This paper lays the groundwork for the development of a new low-cost IC for control of BLDC motors. A simple novel digital pulsewidthmodulation control has been implemented for a trapezoidal BLDC motor drive system. Due to the simplistic nature of this control, it has the potential to be implemented in a low-cost applicationspecific integrated circuit. The novel controller is modeled and verified using simulations. Experimental verification is carried out using field-programmable gate arrays to validate the claims presented.
Speed Control using PWM Technique in BLDC Motor
The performance analysis of speed control in BLDC Motor using arduino PWM technique is carried out in this paper. PWM technique is most widely practiced strategy in controlling the speeds of motor as it has the advantages of consuming low power, can utilize high frequency, high power handling capability and less noise interference. At the same time BLDC motors are considered for its high energy efficient operation and less maintenance. Pulse width modulation works by varying the motor pulses ON-OFF by adjusting the duty cycle for a fixed high frequency signal. Hence in this paper PWM controller algorithm in microcontroller's digital outputs is implemented to the three phase inverter to regulate the speed in BLDC motor in open loop control without making the system complex. The speed control model was performed in both Hardware circuit and (MATLAB/Simulink) software, and the results were analyzed and recorded.

Residential and commercial appliances such as refrigerators and air conditioning systems have been using conventional motor drive technology. The machines in these applications typically have low efficiencies and high maintenance. Development of advanced motor drives has yielded increases in efficiency and reliability. A Brushless DC (BLDC) drives are known for higher efficiency, lower maintenance and higher cost. In this paper presents a proposed method for speed control of BLDC motor using Digital PWM and PI with Fuzzy logic controller. This digital control treats BLDC motor as a digital system and regulates speed with the help of two predefined state variables techniques, which makes the concept of controller extremely simple for design and implementation. The main disadvantage of DC motor is sparking problem in brush but if using BLDC motor solve this problem. PI with Fuzzy is very nice and good concept for speed control of motor because this concept is combination of convention and modern technique. The key advantage of Fuzzy logic controller is switching is possible at different stage, and key advantage is change the value of P and I and regulate the speed of motor. The main advantage of Digital PWM is control the speed without change the voltage and current that's why only change the width of plush and reduce the losses related to current. If we apply the conventional methods generally some resistance are connected in series of supply that case change the value of resistance and regulate the speed of motor. But using this methods losses is increase but if we used the Digital PWM and PI with Fuzzy logic controller and find out which one is best for speed controller of BLDC motor.

Brush Less Direct Current (BLDC) motors are attaining higher priority in industrial automation, computers, aerospace, military, household appliance and traction applications because of its high efficiency, high power density and low maintenance cost. This makes the control of BLDC motor in all the four quadrants very vital. To control a BLDC machine, it is generally required to measure the speed and position of rotor by using the sensor. Using the measured value of rotor position, each inverter phase acting at precise time will be commutated. This paper deals with the digital control of three phase BLDC motor in all four quadrant operation. The motor is controlled in all the four quadrants without any loss of power; in fact energy is conserved during the regenerative period. This energy is stored in a battery storage system during regenerative period and can be fed back to the inverter mains during shortage of supply from the source.
