Sparrow search optimization of longitudinal stabilization strategy for wave piercing catamarans
This work presents a ride control system utilizing T-foil and stern flaps to improve the longitudinal stabili-ty of wave piercing catamarans(WPCs)under severe conditions.Additionally,it delves into optimizing the rele-vant control parameters of the system to achieve better stabilization.This paper adopts a control strategy combining linear quadratic regulator(LQR)and hybrid sparrow search algorithm(HSSA)to design the controller.Then,a new swarm intelligence algorithm,the sparrow search algorithm(SSA),along with its improved variant,is applied to optimize the weight matrix of the LQR controller.By comparing these methods,the study verifies the effective-ness of the designed attitude control system and the efficiency of the improved intelligent algorithm strategy.The re-sults show that the controller based on hybrid SSA exhibits good adaptability,fast convergence speed,and high pre-cision in the optimization process,providing valuable insights for engineering practice.
