Design of Disturbance Cancellation State Observer for Driving Induction Motor

유도전동기 운전에 대한 외란상쇄 상태 관측기 설계

This paper described a robust control of an induction motor using a disturbance cancellation observer of a feedforward control. The speed response of conventional PI controller characteristic is affected by variations of load torque disturbance. In the proposed system. the speed control characteristic using a feedforward control isn't affected by a load torque disturbance.
