带扩张观测器的新型滑模导引律
A new sliding mode guidance law based on extended state observer
摘要
Abstract
To overcome the effect of target maneuvering and dynamic characteristics as guidance accuracy in guidance process, a guidance model with dynamic characteristics considered was firstly established. Based on the model, an adaptive sliding mode guidance law consideriny dynamic characteristics and target maneuvering was designed. Then, an extended observer was used to es-timate the guidance message such as the rate of line-of-sight ( LOS) , acceleration of LOS, maneuvering acceleration and accelera-tion rate of target. The result of simulation shows that the extended observer has fast speed of convergence, high accuracy of estima-tion and good ability of anti-jamming. The guidance law designed has better guidance performance than that of proportional naviga-tion guidance ( PNG) , augmented proportional navigation guidance ( APNG) and sliding mode guidance ( SMG) in different condi-tions of target maneuvering.关键词
