空间电子设备热分析与散热设计

Position control for dual-loop direct drive system

在机载、星载、航空环境中使用的空间电子设备由于外形尺寸较小,重量受限以及电磁兼容性要求较高等原因,其冷却一般只能依靠传导、辐射或强迫对流来完成。这里根据实际使用环境,着重讨论的是传导、辐射散热技术。

The speed inner loop and the position outside loop are the two basest loops of most position control.Both the design of the two loops and the influence of some nonlinear factors to direct drive position control system are analyzed.According to the computer simulation of the analysis,the result of the experiment is shown correctly.It is shown that the analysis is authentically.
