Wind and wave dynamic loads might cause
undesirable vibrations that affect the structure integrity and system performance of floating offshore wind turbines. This
paper addresses the problem of dynamic load mitigation by using semiactive control techniques with the tuned liquid column
dampers placed on the turbine’s tower. The control law is formulated based on the mixed H2/H∞ methods for ensuring the system stability and reliability. Furthermore, the proposed controller only uses output feedback so as to avoid the dependence on the knowledge of the states of the system.
