Abstract
The paper presents a sensorless vector control method for a permanent magnet synchronous motor when the output voltage of the PWM inverter is filtered by an LC filter. The dynamics of the LC filter are taken into account in the design of the controller and adaptive full-order observer. The use of the output filter does not require additional current or voltage measurements. The speed adaptation is based on the estimation error of the inverter output current. Linearization analysis is used to design an observer that enables a wide operation region. Simulation and experimental results show the functionality of the proposed control method.
