摘要

为解决低阶反馈控制高阶系统的合理性问题,利用基于闭环系统时间尺度特性分析方法,分析了控制性能指标中权系数对六阶滚转驾驶仪系统时间尺度特性的影响,讨论了原系统二阶、四阶控制对反馈状态的选取与系统当前慢模态的差别,对不同控制的控制性能进行了仿真对比。结果表明:只有通过设计控制性能指标中的权系数,使得反馈状态变量完全包含当前系统慢模态时,对系统的降阶控制才能达到控制性能要求。

Abstract

To solve rationality problem using low order feedback to control high order system, a method of system decomposing based on closed-loop time scale characteristic was used. The influence of performance index weights on sixth order roll autopilot system characteristic was analyzed. The differences of feedback state choosing between second order, fourth order and current system reduced order were discussed, and the performances were simulated and compared respectively. The results show that: Only if the feedback states contain all slow modes through design of performance index weights, the reduced control can achieve the performance requirement.

Key words： two-scale system; LQR design; reduced control; weights
