Impaired feedforward control of movements in pianists with focal dystonia [PDF]
Frontiers in Neurology, 2022 Learning accurate and fast movements typically accompanies the modulation of feedforward control. Nevertheless, it remains unclear how motor skill learning modulates feedforward control, such as through maladaptation of the sensorimotor system by ...

Feedforward control in children with cerebral palsy and association with white matter integrity [PDF]
Frontiers in NeurologyBackgroundPrecise upper limb movements required for daily activities rely on feedback and feedforward control mechanisms. In children with cerebral palsy (CP), damage to white matter tracts impairs motor execution and sensorimotor control.

Temporal prediction and feedforward control in cerebellar ataxia during spontaneous, instructed, and adaptive auditory-motor coupling while walking [PDF]
Scientific ReportsAuditory-motor coupling, the entrainment of movement to an auditory stimulus, involves processes of temporal prediction and feedforward control. The cerebellum is central to these mechanisms, with deficits contributing to ataxia, characterized by ...

Phase Compensator Combined Feedback Control to Mitigate Dynamic Hysteresis in Piezoelectric Actuators [PDF]
MicromachinesThe inherent dynamic hysteresis nonlinearity of piezoelectric actuators severely degrades the control accuracy of micropositioning systems. This paper proposes a composite control method based on a phase compensator and polynomial correction.

An improving control strategy for grid -connected current in weak grid [PDF]
E3S Web of Conferences, 2021 The traditional proportional feedforward control strategy can suppress the low order harmonics in the strong power grid, but in the weak power grid environment, the grid impedance will have an adverse impact on the stability of the system, resulting in ...

Model-based design of a wave-feedforward control strategy in floating wind turbines [PDF]
Wind Energy Science, 2021 Floating wind turbines rely on feedback-only control strategies to mitigate the negative effects of wave excitation. Improved power generation and lower fatigue loads can be achieved by including information about incoming waves in the turbine controller.

Trunk Angle Modulates Feedforward and Feedback Control during Single-Limb Squatting
Journal of Functional Morphology and Kinesiology, 2021 Trunk positioning and unexpected perturbations are high-risk conditions at the time of anterior cruciate ligament injury. The influence of trunk positioning on motor control responses to perturbation during dynamic performance is not known. We tested the

Training Reflexes Using Adaptive Feedforward Control
IEEE Open Journal of Control Systems, 2023 We consider the problem of mixed feedforward and feedback based disturbance rejection, where the feedforward measurement only provides a partial reconstruction of the disturbance.
