摘要：

研究了一种构造增广比例导引律的方法. 采用具有较强滤波功能的跟踪–微分器来估计视线角速度和视线角加速度，并将信号延迟环节和指令“软化”环节构成导引耦合器来消除跟踪–微分器过渡过程对导引性能的不利影响. 给出了几种典型跟踪–微分器构造增广比例律时的应用方法，针对典型跟踪–微分器的优缺点，提出了一种简洁快速无振荡跟踪–微分器，并将其用于增广比例导引. 仿真实验表明，具有跟踪–微分器结构的增广比例导引方案有良好的导引性能，且简单可行.

Abstract:

A new approach of constructing augmented proportion navigation (APN) is investigated. Light of sight (LOS) angle velocity and acceleration are estimated using a tracking differentiator (TD) with filtering function. A coupler is constructed with a delay section and command softening sector to eliminate the bad effects of TD’s transient process on guidance performance. Some typical applications of TDs are given. A new terse fast TD without chattering is designed based on the merits and drawbacks of typical TDs. Simulation results show that APN with
TD has good guidance performance, and is simple to implement.

Key words: augmented proportion navigation, tracking differentiator, estimation of LOS angle acceleration, coupler, linear region
