| Research Abstract |
We studied the speed sensorless vector control of AC motors using DC link current. At first, we proposed a simplified sensorless vector control of induction motor. We developed a method which estimate phase currents from DC link current and pulse width modulation (PWM) signals. This method is confirmed by simulation results which are obtained by considering PWM. The developed method was tested by experimental systems and good transient responses are obtained without using phase currents. Furthermore, we proposed a simplified sensorless vector control of an interior permanent magnet synchronous motor (IPMSM). This method is tested by experimental system. It is confirmed that the experimental transient responses are very close to simulation results which consider PWM. Since quick responses are obtained, the proposed method is useful for industrial applications.
