Disturbance observer-based robust and fast speed controller for induction motors
1990 / IEEE / 0-87942-553-9
This item was taken from the IEEE Periodical ' Disturbance observer-based robust and fast speed controller for induction motors ' A zeroing technique with an equivalent disturbance observer and a predictive controller were combined and applied to robust and fast speed control for induction motors to which flux vector control is applied. It was experimentally confirmed that the proposed control system is insensitive to system parameter variations, external load torque changes, and flux vector control failure and that it yields a quick time response. It is superior to a conventional PI controller and is easily designed. The use of the same technique for suppressing mechanical vibrations of mechanical loads coupled with an induction motor is also discussed.<
