Abstract

To eliminate the effect of load oscillation caused by cross-link coupling of loading force between multiple nodes in the static loading test of wind turbine blades

a proportional-integral-derivative（PID） decoupling control strategy based on an intelligent optimization algorithm with self-tuning parameters is proposed. Firstly

the mathematical model

between multi-node loading force and the deflection variation of multiple nodes is established

and the algorithm-free control loading of a 71.5 m blade is taken as an example to reveal the cross-link coupling response characteristics. Secondly

combining the variable speed integral and incomplete differential PID control strategy

an improved Beetle Antennae Search algorithm is proposed for the online self-tuning of PID parameters in the nonlinear loading process. Finally

the proposed control strategy is applied to a seven-node static load proof test of 110.5 m wind turbine blades. The results show that the control strategy can effectively reduce the multi-node cross-link coupling

meet the requirements of coordination control of loading force

and realize stable loading of large blade static loading test.
