Resumen:
In this paper a novel time-based adaptive secondorder
sliding mode (SOSM) technique to optimise the efficiency
of a variable-speed wind turbine is developed and analised. A
revisited form of a recent time-based adaptation algorithm is
proposed to deal with the characteristics and control requirements
of the wind energy conversion system (WECS), particularly
model uncertainties and fast disturbances due to gusty
wind effects. The revisited algorithm is based on appropriate
receding-horizon adaptation time windows rather than on fixed,
adjacent and non overlapping ones. This modification, which
enhances the reactivity of the adaptation strategy against fast
varying uncertainties, represents the main theoretical novelty
of this work. The proposed controller is extensively assessed
through computer simulation over a full-order realistic model
of the WECS under study.
