Design of Connectivity Preserving Flocking Using Control Lyapunov Function
Journal of Robotics, 2016 This paper investigates cooperative flocking control design with connectivity preserving mechanism. During flocking, interagent distance is measured to determine communication topology of the flocks.

Mathematics, 2021 In this paper, we propose a Sectorial Fuzzy Controller (SFC) with a feedforward compensation of the robot dynamics in joint space, evaluated at the desired angular positions, velocities, and accelerations, applied to the trajectory tracking of all ...

Global finite-time stability of differential equation with discontinuous right-hand side
Electronic Journal of Qualitative Theory of Differential Equations, 2018 In the paper new sufficient conditions for global finite-time stability of a stationary solution to differential equation with discontinuous right-hand side are given. Time-dependent Lyapunov function which is only continuous is used.

Mathematics, 2020 State observers for systems having Lipschitz nonlinearities are considered for what concerns the stability of the estimation error by means of a decomposition of the dynamics of the error into the cascade of two systems. First, conditions are established

Computation and Verification of Lyapunov Functions [PDF]
SIAM Journal on Applied Dynamical Systems, 2015 Lyapunov functions are an important tool to determine the basin of attraction of equilibria in Dynamical Systems through their sublevel sets. Recently, several numerical construction methods for Lyapunov functions have been proposed, among them the RBF (Radial Basis Function) and CPA (Continuous Piecewise Affine) methods. While the first method lacks a

Nonlinear Control Strategy of MMC-RPC Based on Lyapunov Function
机车电传动, 2021 In order to comprehensively control the power quality in the traction power supply system, based on the power compensation vector diagram, the power relationship between the left and right power supply sections of the V/v traction transformer was ...

Torque Saturation in Bipedal Robotic Walking Through Control Lyapunov Function-Based Quadratic Programs [PDF]
IEEE Access, 2013 This paper presents a novel method to address the actuator saturation for nonlinear hybrid systems by directly incorporating user-defined input bounds in a controller design. In particular, we consider the application of bipedal walking and show that our

Lyapunov functions and topological stability
Journal of Differential Equations, 1980 This paper contains some results on topological stability (see [2, 31) that generalize those obtained in [2] much in the same way as Lyapunov’s direct theorem generalizes the asymptotic stability results of the hyperbolic case: if at a critical point, the linear part of a vector field has proper values with negative real parts, the point is ...

Study of finite amplitude capillary waves stability
MATEC Web of Conferences, 2018 The direct Lyapunov method is used to study capillary waves. The dynamic equations of the capillary wave are presented in the form of an infinite Euler-Lagrange chain of equations for the Stokes coefficients.
