A multielement boundary-value problem with a piecewise-smooth shift on a piecewise-Lyapunov contour for a function analytic in a domain [PDF]

open access: closedUkrainian Mathematical Journal, 1990
In an Lp-formulation (1 < p < ∞) there is constructed for a function ϕ (z) analytic in a multiconnected domain with a piecewise-Lyapunov boundary Γ a Noether theory of the boundary-value problem $$a (t) \varphi (t) + b (t) \varphi [\alpha (t)] + d (t\overline {) \varphi (t) } + e (t) \overline {\varphi [\alpha (t)]} = f(t), t \varepsilon \Gamma ,$$

An Active Contour Model Based on Local Pre-Piecewise Fitting Bias Corrections for Fast and Accurate Segmentation

IEEE Transactions on Instrumentation and Measurement, 2023
The lack of grasp of the image information and the unstable fluctuation of the model energy may cause segmentation failure of the active contour model (ACM). Minimizing the impact of these two factors is critical.

Reachable set estimation for discrete-time T-S fuzzy singular systems based on Piecewise Lyapunov function

Chinese Control and Decision Conference, 2018
This paper is concerned with the problem of reachable set estimation for discrete-time T-S fuzzy singular systems with bounded input disturbances. Based on the Piecewise Lyapunov Function (PLF) method, a improved sufficient condition is established in ...

Online Learning Based Shape Control for a Soft Manipulator Based on Spatial Features Feedback

IEEE Robotics and Automation Letters
Although soft manipulators are endowed with compliance and flexibility, most control strategies focus on end-effector control and lack shape control ability. This letter aims to design a shape controller for the soft manipulator.

Robust Stabilization for Discrete Uncertain Takagi–Sugeno Fuzzy Systems Based on a Piecewise Lyapunov Function

, 2014
This article investigates the robust H∞ fuzzy output-feedback control problem for a discrete Takagi–Sugeno (T–S) fuzzy system with uncertainties. By constructing a discrete piecewise Lyapunov function in each maximal overlapped-rule group, the systematic
