The double‐gimbal control moment gyro (DGCMG) demands that the gimbal servosystem should have fast response and small overshoot. But due to the low and nonlinear torsional stiffness of harmonic drive, the gimbal servo‐system has poor dynamic performance with large overshoot and low bandwidth.

Joint Dynamics Modeling and Parameter Identification for Space Robot Applications
Long‐term mission identification and model validation for in‐flight manipulator control system in almost zero gravity with hostile space environment are extremely important for robotic applications. In this paper, a robot joint mathematical model is developed where several nonlinearities have been taken into account.

Performance of Magnetic-Superconductor Non-Contact Harmonic Drive for Cryogenic Space Applications [PDF]
Harmonic drives are profusely used in aerospace mainly because of their compactness and large reduction ratio. However, their use in cryogenic environments is still a challenge. Lubrication and fatigue are non-trivial issues under these conditions.

FEM Analysis of Stress Distribution in the Hermetic Harmonic Drive Flexspline [PDF]
The paper deals with the numerical stress calculation in the flexspline tooth rim of the harmonic drive. Due to the complex geometry of the toothed ring in the flexspline, the teeth were modeled as a ring, which height corresponded to the particular stress concentration in the teeth.
