Abstract

Abstract
This paper presents a comparison between sliding mode observer and model reference adaptive system based sensorless position and speed control of permanent magnet synchronous motor. In traditional sliding mode observers, signum function which is used as switching function causes chattering effect. For reducing chattering effect low pass filter is used but this filter introduces a phase delay. In order to overcome these problems a sigmoid function is used instead of signum function in sliding mode observer based control method. In model reference adaptive system based control method, it is purposed to make zero error between the reference model and adjustable model. Popov’s super stability theorem is used for the stability of model reference adaptive system control method. Both of the control methods are simulated with Matlab/Simulink.
