Driving Constant Speed of Induction Motor using Disturbance Cancellation Observer

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