Closed-Loop FES Control of a Hybrid Exoskeleton during Sit-to-Stand Exercises: Concept and First Evaluation

Actuators, 2023
Rehabilitation of paralysis caused by a stroke or a spinal cord injury remains a complex and time-consuming task. This work proposes a hybrid exoskeleton approach combining a traditional exoskeleton and functional electrical stimulation (FES) as a ...

Dynamic complexity of a slow-fast predator-prey model with herd behavior

AIMS Mathematics, 2023
The complex dynamics of a slow-fast predator-prey interaction with herd behavior are examined in this work. We investigate the presence and stability of fixed points. By employing the bifurcation theory, it is shown that the model undergoes both a period-

Stochastic Hybrid Control

Journal of Mathematical Analysis and Applications, 2000
The authors consider a complicated version of controlled stochastic systems. The time \(t\) is measured continuously. The state of the system is represented by a continuous variable \(x\) and a discrete variable \(n\). Also, the control has two parts, a continuous type control \(v\) that is a measurable stochastic process and a discrete-type (or ...

A Simple Critical Response Evaluation Method for Base-Isolation Building-Connection Hybrid System Under Double Impulse as Representative of Near-Fault Ground Motion

Frontiers in Built Environment, 2021
We revisit a unique building system including a base-isolation, building-connection hybrid control system. The base-isolation system withstands pulse-type earthquake ground motions effectively and the building-connection system resists long-duration ...

Robust hybrid global asymptotic stabilization of rigid body dynamics using dual quaternions [PDF]

, 2018
A hybrid feedback control scheme is proposed for stabilization of rigid body dynamics (pose and velocities) using unit dual quaternions, in which the dual quaternions and veloc- ities are used for feedback.

A review of orbital space robots on its technical aspects [PDF]

INCAS Bulletin, 2019
An automated shuttle is an unmanned robotics system, generally under telerobotic control. A mechanical robotic system intended to make logical conclusions is regularly called a space probe.
