|Abstract:||Aimportant part of a flight simulator is its
control loading system, which is the part
that emulates the behaviour of an aircraft as
experienced by the pilot through the stick.
Such a system consists of a model of the
aircraft that is to be simulated and a stick that is
driven by an electric motor. To make the
simulation as realistic as possible, the
simulator stick should behave in the same way
as the stick in the real aircraft.
However, due to the properties of the motor
and the stick, small irregularities can be felt
when the stick is moved, which do not occur in
a real aircraft. Probable causes of these
irregularities are cogging in the motor and
small imperfections in the transmission.
Both disturbances have a reproducible nature.
Because the disturbances are reproducible,
feedback error learning control is used for
control. The learning controller consists of two
neural networks. One neural network is used to
compensate the unknown friction and is
operated in feed-forward. The other neural
network compensates cogging and
imperfections in the transmission and is
operated in feedback. Experimental results
showed that the learning controller is able to
compensate the disturbances.
