| 摘 要： | 提出了一种自适应进化策略算法(AES),该算法利用适应度值控制变异步长的自适应调整,从而提高了进化策略的搜索效率和精度。将AES算法和粒子滤波(PF)相结合,提出了基于自适应进化策略采样的粒子滤波算法(AESPF)。该算法将AES应用于粒子重采样,以保证粒子的有效性和多样性。通过仿真计算表明,提出的算法可以有效提高滤波性能。

| Abstract: | An adaptive evolution strategies(AES)algorithm is first proposed.In the algorithm,Adaptive adjustment of mutation step is controlled by fitness to improve searching efficiency and precision.Then a particle filter based on adaptive evolution sampling(AESPF)is proposed by combining AES and particle filter(PF),AES is applied to particle resampling to keep the validity and variety of particles in the algorithm.Simulation results indicate the algorithm can effectively improve the filter performance. |
