Abstract
In the motion control field, a disturbance observer-based
disturbance canceling control is often used as a robust control
methodology. However, this method is nothing more than an alternative
design of an integral controller, and the robust stability issue cannot
be directly accounted for. In this paper, an extended
H∞ control scheme is proposed as a new robust motion
control method which achieves the disturbance cancellation ability and
guarantees robust stability automatically
