Direct instantaneous torque control of three phase 6/4 switched reluctance generator operating at low speeds

, 2019
In this paper, the direct instantaneous torque control strategy (DITC) is applied for the switched reluctance machine (SRM) operating as a generator at low speeds. The firing angles remain fixed in the decreasing part of the inductances.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,
