ABSTRACT Quadrupedal robots operating in unstructured environments require adaptive control systems that can handle diverse terrain conditions without prior surface characterization. This paper presents an integrated control architecture that combines Model Predictive Control (MPC) with adaptive impedance control and SINDy‐based model corrections for ...

Generalized design method of highly-varied-helix end mills for suppression of regenerative chatter in peripheral milling [PDF]
Peripheral finishing of hardened steel by milling has recently been introduced to the machining field, but often causes severe chatter vibration due to high specific cutting force and low stiffness of slender end mills.

Abrasion Monitoring and Automatic Chatter Detection in Cylindrical Plunge Grinding
Using conventional grinding wheels, wheel-sided chatter vibration is one of the limiting factors in terms of productivity and surface fin-ish. Initial vibration related to the dynamic behavior of the machine tool copy on the grinding wheel and its ...

Privacy‐Preserving Data‐Driven Distributed MPC for Heterogeneous Nonlinear Multi‐Agent Systems
ABSTRACT Distributed model predictive control (DMPC) is a cornerstone for coordinating multi‐agent systems, yet simultaneously ensuring data privacy, handling unknown nonlinear dynamics, and managing heterogeneous constraints remains an open challenge.

Sliding Mode Control and Observation for Upper Limb Robotics Rehabilitation
ABSTRACT Stroke is a leading cause of upper limb motor impairments, which often require rehabilitation. General purpose robotic manipulators enable effective therapy through exercises such as Center Out Point‐to‐Point (CO‐PTP) and Teach‐and‐Track (TT), which respectively demand accurate estimation and rejection of the interaction force exerted by the ...

On the stability of high-speed milling with spindle speed variation [PDF]
Spindle speed variation is a well-known technique to suppress regenerative machine tool vibrations, but it is usually considered to be effective only for low spindle speeds.

AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system
Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Abstract This paper investigates the role of semantic features of noun and adjective bases in determining the grammatical behaviour of Ancient Greek denominal and deadjectival verbs in *‐ye/o‐. The paper adopts a lexicalist framework (Rappaport Hovav & Levin 1998) and examines how the event schema, actionality, telicity and voice of derived verbs are ...
