| Outline of Final Research Achievements |
AC Motors which are divided into induction motor and synchronous motor are used widely for electrical equipments. In this case, an encoder is used to detect the speed and position for the vector control which controls electromagnetic torque instantaneously. In this research, the vector control is realized without using the encoder by estimating the speed and position. As the result, the system size is minimized and the sensor cable is removed. We have proposed a simplified encoderless vector control methods for not only the induction motor but permanent magnet synchronous motor. Especially, an estimation method of stator resistance and simple configuration of current and speed controllers are developed theoretically and experimentally. A linear model is useful for the design of controllers.
