Abstract The orientation of reaction wheels and their individual maximum torque capacity limits the agility of a rigid body. However, maximizing the isotropic torque envelope can underestimate the true capability of the system because the inertia properties are not fully considered. This is true even when performing eigenaxis maneuvers with isotropic acceleration and rate limits. Improvement in agility is possible when compared to conventional principal axis orientation of three orthogonal reaction wheels. Reorienting the reaction wheels while maintaining orthogonality can increase agility available for slew maneuvers. This paper uses the agility envelope as a tool in developing analytical equations for the optimal reaction wheel orientation to maximize agility, which can be up to 36% more than conventional methods. The equations and corresponding design curves are also presented for any system based on the normalized Inertia Ratios.

提高正交反作用轮姿态控制系统的敏捷性

摘要 反作用轮的方向及其各自的最大扭矩容量限制了刚体的灵活性。然而，最大化各向同性转矩包络会低估系统的真实能力，因为没有充分考虑惯性属性。即使在执行具有各向同性加速度和速率限制的特征轴机动时也是如此。与传统的三个正交反作用轮的主轴方向相比，可以提高灵活性。在保持正交性的同时重新定向反作用轮可以增加可用于回转操纵的敏捷性。本文使用敏捷包络作为开发最佳反作用轮方向的分析方程的工具，以最大限度地提高敏捷性，比传统方法高出 36%。
