Shared internal models for feedforward and feedback control.
A child often learns to ride a bicycle in the driveway, free of unforeseen obstacles. Yet when she first rides in the street, we hope that if a car suddenly pulls out in front of her, she will combine her innate goal of avoiding an accident with her learned knowledge of the bicycle, and steer away or brake. In general, when we train to perform a new motor task, our learning is most robust if it...
متن کاملStructural learning in feedforward and feedback control.
For smooth and efficient motor control, the brain needs to make fast corrections during the movement to resist possible perturbations. It also needs to adapt subsequent movements to improve future performance. It is important that both feedback corrections and feedforward adaptation need to be made based on noisy and often ambiguous sensory data. Therefore, the initial response of the motor sys...
متن کاملFeedforward and feedback processes in motor control.
In this study, we utilized functional magnetic resonance imaging (fMRI) to examine which brain regions contribute to feedback and feedforward motor control processes. Several studies have investigated the contributions of cortical and subcortical brain regions to motor performance by independently varying factors such as movement rate, force, and speed, and observing the neural responses. Such ...
متن کاملFeedback and Feedforward Tracking Control for Networked Control Systems
Abstract— In this paper, we investigate the feedback and feedforward tracking control problem for networked control systems under the discrete-time framework. The network-induced delays both on the network links from sampler to the controller and from the controller to the actuator are considered. By studying the network property, we assume that there is a probability for the occurrence of each...
متن کاملGenetic Feedforward-Feedback Controller for Functional Electrical Stimulation Control of Elbow Joint Angle
Background: Functional electrical stimulation (FES) is the most commonly used system for restoring functions after spinal cord injury (SCI). Objective: In this study we investigated feedback PID and feedforward-feedback P-PID controllers for regulating the elbow joint angle. Methods: The controllers were tuned based on a nonlinear muculoskeletal model containing two links, one joint with one de...
