| Abstract |
This paper proposes a new speed controller based on the two degrees of freedom control method for motor drives. In order to overcome the stability problem caused by the sampling time and dead time of a conventional digital PI speed controller, a reference system model which has a desirable dynamic performance is incorporated. In this system model, the load disturbance is compensated with the disturbance estimater, which estimates the load disturbance from the actual motor speed. By making use of the torque reference generated from the system model, the fast response speed control can be realized. This new speed controller has a great advantage when applied for the motor drives with high inertia load such as paper mills or steel processing lines.
