An optimization algorithm for antenna array shape adjustment based on nonlinear finite element method

In this paper, based on the nonlinearity of the structure, the actuators are arranged at the struts of the antenna structure, and the genetic algorithm is used to design the hierarchical profile control optimization algorithm considering the optimal actuator arrangement and optimal control quantity calculation. The finite element simulation results show that the profile accuracy can be significantly improved by actuator arrangement, and the control range of profile accuracy increases with the increase of actuator arrangement. However, with the increase of the number of actuators, the improvement effect of the profile accuracy gradually decreases. Therefore, the effect of the number of actuators in the range of ten to 25 is better.
