A Comparative study on the effectiveness of sensor and sensor-less based techniques for a BLDC Motor drive with PI Controller

Drive is a framework containing different components which control the control the motion of electrical machines in the required condition. The converter provides the required power passes from an electrical voltage supply to the motor. In recent past semiconductor technology growing very fast, resulting from the compact, powerful AC and DC motor drives made. The essential characteristic likely high efficient, smooth operation, high reliability, direct control renders the brushless DC motor best choice for the consumer and industrial application. In the most of recent research work, rotor position is identified by wearing a Hall transducer on the nearby the stator winding in the BLDC Motor and developing the sensorless control of BLDC motor drive system is remaining the important issues. In this paper compare the sensor and Terminal Voltage sensing method of the sensor-less technique control for a Brushless DC Motor drive with PI controller. MATLAB/Simulink2010a software tools are used for modeling, simulating the above the proposed system.
