论文部分内容阅读
本文首先讨论圆波导。多模自跟踪系统的交叉耦合及电轴漂移(零漂),这是对文献[1]讨论的问题进行再认识。对上述问题,[1]采用和差电压共轭相乘的办法进行计算,这与实际电路原理不符,且公式絮繁,因而值得商榷.本文则采用复数相除的办法进行重算,得到了简洁的描述公式.[4,5]实质上用的是复数除法. 文章的后半部分讨论了交叉耦合对系统稳定性及动态滞后误差的影响,研究用动态误差常数表示系统开环传递函数的方法,以及速度补偿减小动态误差的原理.
This article first discusses the circular waveguide. Cross-coupling of multi-mode self-tracking systems and drift (zero drift) of the electrical axis is another recognition of the issues discussed in [1]. For the above problem, [1] adopts the method of multiplying the difference voltage conjugate, which is inconsistent with the actual circuit principle and the formula flutter.Therefore, it is debatable.In this paper, A simple description of the formula [4,5] is essentially the use of complex division.The second half of the article discusses the cross-coupling on the system stability and dynamic lag error, the study of dynamic error constant that the system open-loop transfer function Method, and speed compensation to reduce the dynamic error principle.
