Model Based Adaptive Piecewise Linear Controller for Complicated Control Systems
Journal of Applied Mathematics, 2014 A model based adaptive piecewise linear control scheme for industry processes with specifications on peak overshoots and rise times is proposed. It is a gain stabilized control technique.

Continuum Mechanics Modeling of Flexible Spring Joints in Surgical Robots
Advanced Robotics Research, EarlyView.A new mechanical model of a tendon‐actuated helical extension spring joint in surgical robots is built using Cosserat rod theory. The model can implicitly handle the unknown contacts between adjacent coils and numerically predict spring shapes from straight to significantly bent under actuation forces.

Revista Facultad de Ingeniería Universidad de Antioquia, 2014 Galvanometer mirror systems are a fundamental tool used in many research fields to deploy curves over virtually any surface. Even though the point-based methodology is the current standard used to achieve this task, it has the shortcoming of using a ...

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

Analysis of Non-Monotonic Piecewise Lyapunov Stability and Semi-PID Design for MIMO Piecewise Affine Systems [PDF]
International Journal of Research and Technology in Electrical IndustryIn this study, we introduce the Non-monotonic Lyapunov (NML) approach, aimed at stability examining and designing stabilizable controller for a specific category of discrete piecewise affine dynamical systems.

A cut finite element method for coupled bulk-surface problems on time-dependent domains
, 2015 In this contribution we present a new computational method for coupled bulk-surface problems on time-dependent domains. The method is based on a space-time formulation using discontinuous piecewise linear elements in time and continuous piecewise linear ...

Counting the Lyapunov inflections in piecewise linear systems* [PDF]
Nonlinearity, 2021 Abstract Following the pioneering work of Iommi–Kiwi and Jenkinson–Pollicott–Vytnova, we continue to study the inflection points of the Lyapunov spectrum in this work. We prove that for any three-branch piecewise linear expanding map on an interval, the number of its Lyapunov inflections is bounded above by 2 ...
