Optimal Tuning of Digital PID Controllers for Commercial BLDC Motors Using the Nelder–Mead Method

open access: yesPower Electronics and Drives
Brushless DC (BLDC) motors are widely used in various applications due to their high efficiency and reliability. Many sensorless BLDC motor drivers, developed using zero-crossing detection of back electromotive force (EMF), eliminate the need for ...

gradient systems [PDF]

open access: yes, 2022
Purpose: Providing accurate gradient currents is challenging due to the gradient chain nonlinearities, arising from gradient power amplifiers and power supply stages. This work introduces a new characterization approach that takes the amplifier and power

Changes in motor unit conduction velocity after unilateral lower‐limb suspension and active recovery are correlated with muscle ion channel gene expression

open access: yesExperimental Physiology, EarlyView.
Abstract The effects of muscle disuse on the propagation of action potentials along motor unit (MU) muscle fibres, a key process for effective muscle activation and force generation, remain poorly understood. The aim of this study was to investigate changes in action potential propagation and to identify biological factors influencing these changes ...

Tonotopically distinct OFF responses arise in the mouse auditory midbrain following sideband suppression

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sounds of different frequencies elicit spatially distinct patterns of neural activity within the inferior colliculus aligned to the tonotopic organization of afferent projections. Sound‐evoked neural responses can be visualized in awake mice that express fluorescent Ca2+ sensors.

Noise‐induced reduction and early recovery of superior paraolivary nucleus sound‐offset responses

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Acoustic over‐exposure transiently disrupts auditory temporal processing in mouse superior paraolivary nucleus neurons. In control conditions, neurons exhibit robust sound‐offset (OFF) responses, which are abolished immediately following noise trauma, indicating impaired temporal encoding.
