Total Energy Shaping for Task-Invariant Control of Lower-Limb Exoskeletons

We present a total energy shaping control methodology for the development of portable lower-limb assistive exoskeletons and orthotic devices that help reduce the human’s effort and augment natural motion. Current robotic exoskeletons restrict joint motion to pre-defined position trajectories during gait rehabilitation; such methods aim to replicate...

High Torque Density Switched Reluctance Motors

Applications like aerospace, automotive and robotics require high torque to volume/weight ratio machines. Permanent Magnet Machines have been considered to be the sole candidates, however, the limitation of the operational temperature, relatively high price, and unstable overseas supply of permanent magnet material limits its massive applications. There...
