acceleration feedback

acceleration feedback

[ak‚sel·ə′rā·shən ′fēd·bak]
(aerospace engineering)
The use of accelerometers strategically located within the body of a missile so that they sense body accelerations during flight and interact with another device on board the missile or with a control center on the ground or in an airplane to keep the missile's speed within design limits.

In this single-subject case study, we present the development and performance evaluation of a control system utilizing COM acceleration feedback to modulate stimulation to the paralyzed musculature of a subject with complete paraplegia undergoing internal postural perturbations.
A control system employing COM acceleration feedback was developed and evaluated for a single SCI subject with an implanted neuroprosthesis for standing function.
Ultimately, an ANN was trained to output optimal changes in the levels of the stimulation (up to 16 implant channels plus 6 surface channels) according to 2 (AP, ML) COM acceleration feedback inputs.
Only positive changes in stimulation were explored because the minimum levels were necessary to maintain basic standing with FNS without acceleration feedback.

Instead of velocity feedbacks, force feedbacks or acceleration feedbacks are used in pneumatic vibration isolation system and in aerospace vibration isolation system [9-11], in order to realize sky-hook damping [12-13].
The MAJ series drives feature core components and features required for next generation drive technology, including acceleration feedback aided positioning system to increase tolerance to rational vibration and temperature variations, an expanded 4 MB data cache, reduced acoustic levels, and a high performance, dual-processor design that greatly improves response time in high-load applications.
The controller con sisted of using proportional COM acceleration feedback to drive an artificial neural network (ANN).
We subsequently addressed excitation-activation coupling during forward simulations with specified perturbations ("Perturbation Simulations" section) with optimal tuning of the feedback controller gains ("Tuning Center of Mass Acceleration Feedback Controller" section) to minimize UL loading in the presence of activation dynamics [18].
With only COM acceleration feedback to modulate stimulation levels, some measure of FNS activation is necessary to maintain the erect set point when no significant accelerations (e.
Acceleration feedbacks were added to each rotating frame with controllers [R.
Pressure, position and acceleration feedbacks were applied.
