Abstract :
The position and velocity sensorless control of brushless DC motors using an adaptive sliding observer is discussed. The sliding observer is robust to measurement noises. The stability of the adaptive scheme is assured, and estimation errors due to parameter deviations are analyzed. A compensation method for parameter deviations is shown. Simulations done to verify the feasibility of the position and velocity sensorless control scheme are discussed
