Sensorless Control of a Brushless DC Motor
This paper uses a new position sensor less drive for brushless DC (BLDC) motors. In conventional sensor less control methods such as the back-EMF detection method, the performance is high only at a high speed range due to the fact that the magnitude of the back-EMF is dependent on the rotor speed. A solution is derived that estimates the rotor position by using an unknown input observer over a ...
متن کاملSensorless Drive of Brushless Dc Motor Based upon Wavelet Analysis
This study tackles to develop a sensorless drive technique for brushless dc motors (BLDC) by using wavelet theory. Initially a BLDC motor with hall sensors is handled. The simulink model of the motor is established and the simulation performances are obtained. Then BLDC motor’s PWM pulses are produced by DS2201 dSPACE digital signal processing (DSP) rapid control prototyping kit. The time domai...
متن کاملSensorless Speed Control of Brushless DC Motor with Fuzzy Based Estimation
This paper describes a simple way to control the Brush Less DC Motor (BLDCM) for electrical applications. To control this machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, acting at any time, must be commutated depending on the rotor position. The position sensors make the motor system more complicated and mechanically u...
متن کاملImplementation of a Novel Brushless DC Motor Drive based on One-Cycle Control Strategy
In this paper, one-cycle control (OCC), as a constant-frequency PWM control strategy for current control of a six-switch brushless dc (BLDC) motor drive is investigated. Developed current regulator is a unified controller and PWM modulator. Employing the one-cycle control strategy, decreases the torque ripple resulted from the conventional hysteresis current controllers and therefore, the vibra...
