Stored waveform adaptive motor control
This study investigates an adaptive control scheme designed to maintain accurate motor speed control in spite of high-frequency periodic variations in load torque, load inertia, and motor parameters. The controller adapts, stores and replays a schedule of torques to be delivered at discrete points …

Models of generalization in motor control
Motor learning for humans is based on the capacity of the central nervous system (CNS) to perform computation and build an internal model for a task. This thesis investigates the CNS's ability to generalize a learned motor skill throughout neighboring spatial locations, its ability to divide the …

Investigation of digital pump/motor control strategies
… on the efficiency of many fluid power systems. Motors are the most common rotary actuators in fluid power systems. State-of-the-art pump/motor units can achieve efficiencies higher than 90% when operating at maximum displacement; however, as the displacement drops, the efficiency of these units …

Characterizing motor control signals in the spinal cord
… generated in the brain and spinal cord for the control of motor function in the forearms. The nature of the central command signal has been debated for many decades with only limited progress. This thesis presents a project that investigated this problem using novel techniques. Rats are …

Sensory-motor control and adaptation in cooperative action
… sensory information about a partner in order to control goal-directed action involving synchronous vertical hand movement. Chapter 1 reviews recent developments in studies of interpersonal interaction and highlights control issues that are critical in cooperative action. In Chapter 2, an …

Meso : a virtual musculature for humanoid motor control
Humanoid behavior requires a system with access to humanoid variables. Our humanoid robot, Cog, has two arms that are structurally similar to those of humans; however, the sensory system only provides a sense of strain and position. This thesis describes a model of the human energy metabolism that …

Neuromuscular modularity and behavioral correlates of motor control
… organizational principles that may subserve the control and learning of forelimb movements. Among these principles, I focused on muscular coordination patterns, motor cortical excitability, and sensorimotor interactions. I found that muscle activity in grasping and reaching behaviors could be …

The effect of subconcussive blows on fine motor control
… has been shown to cause immediate impairment in motor control. However, the effect of subconcussive blows is much more controversial. The clinically accepted recovery time from concussion is 7-10 days. However, recent studies involving EEG and complex motor tasks have revealed deficits up to 12 …

Choking under pressure : attention and motor control in performance situations
… in this study, the nodalpoint hypothesis of motor control (Hossner & Ehrlenspiel, 2006) was taken to predict movement changes on three levels of analysis at certain “nodalpoints” within the movement sequence. Performance in two different laboratory tasks was assessed with respect to overt …

The long term effects of concussion on fine motor control
… impairment in neurocognitive function and motor control. A widely accepted recovery time from concussion is 7-10 days. However, late life health issues and evidence of chronic inflammatory scar tissue buildup in the brain have been linked to repeated head trauma. In recent …
