摘要:设计了一种改进型Fal函数滤波器,并分析了其滤波性能.仿真结果显示,该滤波器具有良好的滤波性能.在此基础上,将改进型Fal函数滤波器与扩张状态观测器(ESO)相结合,设计出一种改进型ESO.对比分析传统型ESO与改进型ESO对正弦信号和阶跃信号中量测噪声的处理能力,仿真结果显示,改进型ESO在抑制噪声干扰与跟踪目标信号方面均表现出更优异的性能.

关键词: Fal函数, 滤波器, 扩张状态观测器

Abstract: A filter based on an improved Fal function was designed,and its filtering performance was analyzed.Simulation results demonstrate that this filter achieves favorable filtering effects.Building upon this,an improved Extended State Observer (ESO) was developed by integrating the improved Fal function filter with the ESO framework.The performance of the traditional ESO and the improved ESO in handling measurement noise in sinusoidal and step signals was compared and analyzed.Simulation results indicate that,compared with the traditional ESO,the improved ESO exhibits superior performance in both noise suppression and target signal tracking.

Key words: Fal function, wave filter, extended state observer
