‘Whip from the hip’: thigh angular motion, ground contact mechanics, and running speed

Biology Open, 2020
During high-speed running, lower limb vertical velocity at touchdown has been cited as a critical factor needed to generate large vertical forces. Additionally, greater leg angular velocity has also been correlated with increased running speeds. However,

Speed control method for dual-flexible manipulator with a telescopic arm considering bearing friction based on adaptive PI controller with DOB

Alexandria Engineering Journal, 2022
A dual-flexible manipulator with a telescopic arm is affected by joint flexibility, load flexibility, and bearing friction, which will cause angular velocity fluctuation.

Design of steering control system maintaining ship's rotation in strong wind (Servo type generalized minimum variance control with adjusting wind effect)

Nihon Kikai Gakkai ronbunshu, 2015
A ship is turned by steering. Then the ship is turned with constant angular velocity against the steering angle. However, the turning angular velocity is varied by blowing strong wind.

AMRTA-X: Grasp Kinematic Analysis during Myoelectric Prehension Orthosis and Body Powered Prehension Orthosis's Usage on Brachial Plexus Injury Patients

Folia Medica Indonesiana, 2021
Brachial Plexus Injury (BPI) results in decreased motor function in upper extremity and leads to reduced hand grasping movement. Orthotic prehension is designed to create artificial grasp movements in paralyzed hand.

Defining the Consistent Velocity of Omnidirectional Mobile Platforms

Machines
The maximum linear (or translational) velocity achievable by an omnidirectional platform is not uniform as it depends on the angular orientation of the motion.

Attitude control of on-orbit capture spacecraft with angular velocity constraint

Xibei Gongye Daxue Xuebao, 2022
Aiming at the attitude control problem of spacecraft in the capturing non-cooperative target process, a dual tracking robust adaptive attitude controller is designed. Firstly, a bounded virtual angular velocity is designed for the kinematics equations to
