PD Controller: Design

PD Controller: Design

In automotive engineering, car suspension systems often employ Proportional Derivative (PD) controllers to enhance performance. PD controllers are utilized to adjust the damping force in response to road conditions. A controller, acting as an amplifier with a constant gain, demonstrates proportional control, with output directly mirroring input.
Designing a continuous-data controller requires selecting and linking components like adders and integrators, which are fundamental in Proportional,...

Motor Unit Stimulation

Motor Unit Stimulation

When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Torque Free Motion

Torque Free Motion

The torque-free motion refers to the movement of a rigid body in space when no external torques are acting upon it. This type of motion can be observed in environments where there are no external forces or frictions, like in outer space. For example, a rotation of Mars in space is a torque-free motion. Mars is an axisymmetric object, meaning it has an axis of symmetry along which it rotates, designated as the z-axis. The rotating frame of reference is defined such that the center of mass of...

PI Controller: Design

PI Controller: Design

Proportional Integral (PI) controllers are a fundamental component in modern control systems, widely used to enhance performance and mitigate steady-state errors. They are particularly effective in applications such as automatic brightness adjustment on smartphones, where they excel at mitigating steady-state errors for step-function inputs. Unlike PD controllers, which require time-varying errors to function optimally, PI controllers leverage their integral component to address residual...

Background:

Developing advanced prostheses is crucial for restoring mobility in amputees.
Powered lower-limb prostheses aim to mimic natural gait dynamics.

Purpose of the Study:

To describe and evaluate a novel running controller for a powered knee and ankle prosthesis.
To assess the prosthesis's ability to replicate essential running gait features.

Main Methods:

Implemented a running controller on a powered prosthesis prototype.
Evaluated the prosthesis with a transfemoral amputee running on a treadmill at 2.25 m/s.
Compared the prosthesis's running kinematics to those of five healthy subjects.

Main Results:

The powered prosthesis and controller demonstrated the ability to provide salient features of a running gait.
Kinematic comparison indicated essential features of a healthy running gait were replicated.

Conclusions:

The developed running controller is effective in enabling a powered prosthesis to achieve a healthy running gait.
