Abstract A new dual-actuator fatigue loading system of wind turbine blades was designed. Compared with the traditional
pendulum loading mode, the masses in this system only moved linearly along the loading direction to increase the
exciting force. However, the two actuators and the blade constituted a complicated non-linear energy transferring
system, which led to the non-synchronization of actuators. On-site test results showed that the virtual spindle
synchronous strategy commonly used in synchronous control was undesirable and caused the instability of the
blade’s amplitude eventually. A cross-coupled control strategy based on the active disturbance rejection algorithm
was… More >
