Brushless DC motors (BLDC) are one of the most widely used types motors, both in industrial and automotive fields. BLDC motor was chosen because it has many advantages over other electric motors. However, its application market, control systems still use conventional controls. This method is easy simple to apply but weaknesses, example that if system state changes, then parameters PID must also...

This article introduces a sort of intelligent brushless DC motor driver and its concrete application in electric bicycle, and discusses the hardware and software design scheme of the controller, and realizes the speed control, over-current protection and battery under-voltage protection of the brushless DC motor. And the experiment result indicates that the control effect is good, and it could ...

Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have a low cost, but effective BLDC motor speed/torque regulator. They are used in Residential and commercial appliances such as refrigerators and air conditioning systems with conventional motor drive technology. A Brushless DC (BLDC) drives are known for higher eff...

This paper presents a new hybrid Cultural Algorithm (CA) based particle swarm optimization (PSO) that converges to a significantly more accurate solution then existing particle swarm optimization and which has also been applied to the linear brushless DC motor PID controller design. The utility of hybrid CA based PSO is demonstrated by determining the optimal proportional-integral-derivative (P...

This paper describes the analysis and design of a low cost three phase inverter brushless dc motor (BLDC) drive.For effective utilization of the developed system, a novel direct current controlled pwm scheme (DPC)is designed and implemented.. The operational principle of the four-switch BLDC motor drive and the developed control scheme are theoretically analyzed and the performance is demonstra...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 This paper presents a performance investigation of bldc motor employing KY converter. Conventional The landsman converter is used to minimize the ripples but the inverter produces high output power ripples, which in turn affect the output of the inverter in The proposed KY converter reduces ripples and smooth dc supply gives to th...
