机载四框架二轴稳定跟踪平台速率稳定回路控制

在机载四框架二轴机载稳定跟踪平台机理分析的基础上，对其速率稳定回路进行了建模研究。在速率稳定回路的校正环节设计中，针对传统的超前滞后校正抗干扰性能差的缺陷，提出了两种控制方法：高阶PI校正以及高阶PI校正加超前校正。并以内俯仰速率稳定控制回路为例进行分析。仿真结果表明，采用高阶PI校正加超前校正不仅具有更好的抗干扰性能，还改善了高阶系统的动态性能。

Control of Stabilization Loop for Four-Gimbal and Two-Axis Airborne stabilization and Tracking Platform

The velocity stabilization loop of the four-gimbal and two-axis airborne stabilization and tracking platform is modeled based on the mechanism analysis. In the design of the correction in velocity stabilization loop,the traditional advanced-lag correction method has the disadvantage of bad anti-jamming ability. In order to improve the anti-jamming ability,two algorithms are proposed,one is a higher-order PI correction,and the other one is a higher-order PI correction together with an advanced correction.
