Comparative Analysis between Digital PWM and PI with Fuzzy Logic Controller for the Speed Control of BLDC Motor

Abstract

 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.
