Prosthetic Control

Prosthetic control is the use of biological signals, sensors, and computational systems to direct the movement and function of an artificial limb, helping users perform purposeful actions. In bioengineering, electrodes may detect residual-muscle activity through electromyography, while embedded algorithms interpret these signals and convert them into commands for motors, joints, or other actuators; sensory feedback can further support control and user awareness. These systems enable movements such as grasping, walking, and position adjustment, while ongoing research seeks more intuitive, reliable, and adaptive interfaces. Improved prosthetic control can enhance independence, reduce cognitive effort, and advance human-machine integration in rehabilitation and assistive technology.

2014

Neural-machine interfaces (NMI) have been developed to identify the user's locomotion mode. These NMIs are potentially useful for neural control of powered artificial legs, but have not been fully demonstrated. This paper presented (1) our designed engineering platform for easy implementation and development of neural control for powered lower limb prostheses and (2) an experimental setup and protocol in a laboratory environment to evaluate neurally-controlled artificial legs on patients with...

In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function. When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...
