This paper deals with sensorless brushless DC motor drive fed by a Cuk converter as a cost-effective solution for low-power applications. The single phase supply is fed to uncontrolled bridge rectifier, which is followed by a Cuk converter used to control the voltage of DC link capacitor that feds the Voltage Source Inverter (VSI). Voltage of the DC link capacitor of Cuk converter is controlled to...
This paper presents a method for estimation of the rotor speed and position of a BLDC motor. As BLDC motors are non-linear systems, Extended Kalman Filter (EKF), an advanced version of the Kalman filter has been used for designing the control algorithm for the motor. In the proposed work, the motor state variables are estimated using an Extended Kalman Filter, using the measurements of the stator...
