TL;DR: In this article, the authors considered a general representation of interconnections when the strength of the interconnection is bounded by a pth-order polynomial in states, and designed two adaptive controllers with partially centralized compensation and a fully adaptive decentralized controller.

TL;DR: In this article, a robust decentralized adaptive controller design for interconnected systems is proposed, where the strength of the interconnections is bounded by a pth-order polynomial in states.

TL;DR: The authors examine the role of adaptive controllers for force control with unknown system and environment parameters and clearly integrate several fundamental issues such as explicit force control, impedance control, and impedance control combined with a desired force control.

TL;DR: In this paper, a decentralized controller design for large-scale uncertain systems with higher-order uncertainties is investigated, where uncertainties are assumed to be bounded by a known or unknown pth-order polynomial in states.

TL;DR: Lumbar puncture for purposes of administering spinal or epidural anesthesia is a complex clinical skill which requires the clinician to precisely correlate a detailed mental map of hidden three-dimensional anatomy with tactile feedback from the spinal needle as it is inserted.
