High performance induction machine control: Methods, limits and solutions
… high speed DTC operation, including excessive torque ripple and diminished torque capability of the drive method. Asymptotic-input-output-decoupling is proposed to improve this erratic DTC performance. The results show that asymptotic decoupling compensates for erratic DTC performance with …

Design of a Proprioceptive Actuator Utilizing a Cycloidal Gearbox
<p>Legged robotics creates the demand for high torque compact actuators able to develop high instantaneous torque. Proprioceptive actuator design theory is a design theory that removes the need for a torque feedback device and relies on the stiffness in the leg for absorbing the high Ground Impact …

Modeling, design, and optimization of permanent magnet synchronous machines
… particular. In addition to the low-speed, high-torque, low-mass requirements on the machines, the act of running results in an unconventional drive cycle that consists of brief periods of high torque followed by long stretches of minimal torque requirement, a performance envelope that is not …

Electromechanical Design and Development of the Virginia Tech Roller Rig Testing Facility for Wheel-rail Contact Mechanics and Dynamics
… the contact patch parameters including force, torque, displacement, rotation, speed, acceleration, and contact patch geometry. A unified communication protocol between the actuators and sensors minimizes data conversion time, which allows for servo update rates of up to 48kHz. This provides an …
