High-speed motor is increasingly used in ultra-high precision machining and high-performance machinery. It necessary to achieve closed-loop control of high-speed order realize control. The high-frequency characteristics have brought great difficulties for its realization performance the hexagonal flux direct torque (DTC) method that can reduce switching frequency power devices researched synchr...

Movement speed is fundamental to all animal behaviour, yet no general framework exists for understanding why animals move at the speeds they do. Even during fitness-defining behaviours like running away from predators, an animal should select a speed that balances the benefits of high speed against the increased probability of mistakes. In this study, we explored this idea by quantifying trade-...

Detecting discontinuities in motion signal distributions is an essential operation of visual systems, contributing to perception and visuo-motor control. Discontinuities can be signalled by a difference in speed, direction or both. We measured how localisation accuracy for a motion defined contour depends on the velocity differences that define it. A vertical motion contour was defined by two f...
