Feedback control of unsupported standing in paraplegia. Part I: optimal control approach [PDF]

open access: yes, 1997
This is the first of a pair of papers which describe an investigation into the feasibility of providing artificial balance to paraplegics using electrical stimulation of the paralyzed muscles. By bracing the body above the shanks, only stimulation of the

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Sensorless Deadbeat Control Strategy With Adaptive Capability for PMSM Drive Machines

open access: yesIEEE Access
This research work designs an adaptive sensorless deadbeat control (AS-DBC) method for permanent magnet synchronous motors (PMSMs). The proposed AS-DBC effectively merges the merits of deadbeat control (DBC) for ensuring fast dynamic response while ...
