基于改进型Fal函数滤波器的扩张状态观测器设计
Design of an Extended State Observer Based on the Improved Fal Function Filter
摘要
Abstract
A filter based on an improved Fal function was designed,and its filtering performance was ana-lyzed.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 func-tion 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.关键词
