Gimbal

Proceedings of the 2021 ACM SIGCOMM 2021 Conference, 2021
Emerging SmartNIC-based disaggregated NVMe storage has become a promising storage infrastructure due to its competitive IO performance and low cost. These SmartNIC JBOFs are shared among multiple co-resident applications, and there is a need for the platform to ensure fairness, QoS, and high utilization.

Model predictive control of three-axis gimbal system mounted on UAV for real-time target tracking under external disturbances

Mechanical Systems and Signal Processing, 2020
The fact that Unmanned Aerial Vehicles (UAVs) move in a specific path and that the camera in the gimbal system mounted on the UAV adhere to the right target attracts the attention of many researchers.

Composite Control for Gimbal Systems With Multiple Disturbances: Analysis, Design, and Experiment

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2023
The proportional-integral (PI) controller has proven to be a remarkably effective control strategy in the servo field. However, it is difficult for PI to handle the problem of multiple disturbances degrading the velocity-tracking capability of the gimbal

Gimbals in the insect leg

Arthropod Structure & Development, 2009
We studied the common kinematic features of the coxa and trochanter in cursorial and raptorial legs, which are the short size of the podomers, predominantly monoaxial joints, and the approximate orthogonality of adjacent joint axes. The chain coxa-trochanter with its short elements and serial orthogonality of joint axes resembles the gimbals which ...
