Improved Active Disturbance Rejection Control for Trajectory Tracking Control of Lower Limb Robotic Rehabilitation Exoskeleton.

2020

Neurological disorders such as cerebral paralysis, spinal cord injuries[acronym](SCI), and strokes, result in the impairment of motor control and induce functional difficulties to human beings like walking, standing, etc. Physical injuries due to accidents and muscular weaknesses caused by aging [english]affectsaffect people and can cause them to lose their ability to perform daily routine functions. In order to help people recover or improve their dysfunctional activities and quality of life after accidents or strokes, assistive devices like exoskeletons and orthoses are developed. Control strategies for control of exoskeletons are developed with the desired intention of improving the qual…

Moderating Effects of Trait Anxiety on Electrodermal Reactions in Different Learning Conditions

1984

This study examined the control of the effects of trait anxiety on GSR during a problem-solving task under different conditions. Of 84 subjects, 39 men and 49 women of mean age 21 yr., 42 were classified as high in anxiety, 42 as low in anxiety. Subjects solved concept-formation tasks at different degrees of difficulty under one of three learning conditions. Low tone, unpleasant loud tone, and unpleasant electric shock provided the three kinds of error feedback. For the ‘low tone’ and ‘electric shock’ as feedback on errors significant differences in GSR values resulted for groups high and low in anxiety with the latter showing higher scores. The relevance of physiological patterns in multi…
