Preface
As an urgent desire has come up for high-precision control in modern engineering
systems, disturbance and uncertainty attenuation has become increasingly impor-
tant and has attracted much attention in both academic and industrial communi-
ties. Traditional feedback-control schemes such as proportional-integral-derivative
(PID) controllers, attenuate disturbances by feedback regulation in a relatively slow
way. In the control community, it is well-known that feedforward control pro-
vides an effective disturbance compensation method that can achieve prompt distur-
bance attenuation. However, the implementation ...
