Abstract：For the path planning of fixed wing UAV with high real-time requirements,time cost is introduced into the optimi-zation model to fit the actual project,and an improved gray wolf optimizer integrating whale optimization algorithm is proposed to complete the optimization solution.On the premise of retaining the gray wolf hierarchy,a random mechanism about candidate wolves is added to improve the ability to jump out of the local optimum.The spiral updating mechanism is introduced while using weight fac-tors to control contraction and expansion.The randomness of the latter is weakened by establishing early warning probability related to the fitness ranking.Finally,the advantages of the improved algorithm in convergence accuracy and convergence speed are quanti-fied in the comparative simulation experiments of path planning in different dimensions.
