Adaptive Human Control Gains During Precision Grip, Erik D. Engeberg
Adaptive Human Control Gains During Precision Grip, Erik D. Engeberg
Mechanical Engineering Faculty Research
Eight human test subjects attempted to track a desired position trajectory with an instrumented manipulandum (MN). The test subjects used the MN with three different levels of stiffness. A transfer function was developed to represent the human application of a precision grip from the data when the test subjects initially displaced the MN so as to learn the position mapping from the MN onto the display. Another transfer function was formed from the data of the remainder of the experiments, after significant displacement of the MN occurred. Both of these transfer functions accurately modelled the system dynamics for a portion …
