ABSTRACT: With the recent trend towards large multi-MW
wind turbines, the role of the control system has become
increasingly important and its design increasingly demanding.
Furthermore, the realisation that not only the performance of
the machine but also the structural loads depend on the
controller, has given research into the control of wind turbines
a new impetus. The extension of the role of the controller to
alleviate structural loads has motivated the exploration of novel
control strategies, which seek to maximise load alleviation by
exploiting the blade pitch system. An overview to raise
awareness of the possibilities and potential of control for multi-
MW wind turbines is presented. The place within the wind
energy technology of the control system and its role as an
integrating technology together with the perspective of the
developers are discussed
