数字式自动驾驶仪复合稳定回路变参数设计与仿真

自动驾驶仪参数设计的传统方法是在不同马赫数下，选取一组控制回路参数，使系统整体性能最优。随着数字式弹载计算机的使用，自动驾驶仪能够很方便地实现系统变参数设计，在不同的马赫数及不同的飞行状态下，通过弹载计算机的解算来实时装订系统参数。本文针对复合稳定回路的特点，探讨了典型复合稳定回路的参数选取方法，并在Matlab环境下进行了仿真计算，旨在为工程应用提供一定的参考。

Variable-Parameter Design and Simulation about Digital Autopilot of Compound Stabilization Loop

The traditional method of selecting parameters in the autopilot system is to find an optimized set which can make the system work well at different Mach numbers. But now the parameters of digital autopilot system can be easily designed, changed and loaded at real-time, at different flying states and at different Mach numbers by missile-borne computer. The features of compound stabilization loop are analyzed to provide a new method for selecting parameters in the closed-loop. All Models and data are simulated with Matlab software to provide a good reference for engineering application.
