Structured Analytic Mappings for Point Set Registration

Wei Feng, Tengda Wei, Haiyong Zheng

Abstract. We present an analytic approximation model for nonrigid point set registration, grounded in the multivariate Taylor expansion of vector-valued functions. By exploiting the algebraic structure of Taylor expansions, we construct a structured function space spanned by truncated basis terms, allowing smooth …

Structured Analytic Mappings for Point Set Registration

Wei Feng, Tengda Wei, Haiyong Zheng

We present an analytic approximation model for non-rigid point set registration, grounded in the multivariate Taylor expansion of vector-valued functions. By exploiting the algebraic structure of Taylor expansions, we construct a structured function space spanned by truncated basis terms, allowing smooth deformations …

Prescribed-Time Impulsive Control of High-Order Integrator Systems

Tengda Wei, Xiaodi Li, Daniel W. C. Ho

This article presents a new design of prescribed-time impulsive controllers for the prescribed-time stability (PTS) of high-order integrator systems with a single control input. To deal with the singularity of the control input matrix, a stability result is established based on the …

Self-Triggered Prescribed-Time Impulsive Control for Nonlinear Systems

Tengda Wei, Min Xue, Xiaodi Li, James Lam

This article presents a new design of self-triggered impulsive control (STIC) for prescribed-time stability (PTS) of nonlinear systems. A prescribed-time convergent function is proposed to determine the impulsive control strength together with the information of the impulsive interval. Different from previous impulsive …

Observer-based event-triggered impulsive control of delayed reaction-diffusion neural networks

Luyao Li, Huan Liang, Tengda Wei

In this paper, we present a novel design of an observer-based event-triggered impulsive control strategy for delayed reaction-diffusion neural networks subject to impulsive perturbation. The impulsive instants of impulsive control are determined in an event-triggered way, and the control strength is designed …

Input-to-State Stability of Impulsive Switched Systems Involving Uncertain Impulse-Switching Moments

Chang Liu, Wenlu Liu, Tengda Wei, Xiaodi Li

Dear Editor, This letter studies the input-to-state stability (ISS) for a class of impulsive switched systems, where uncertain impulse-switching moments are involved. The robustness of ISS with respect to the perturbations of the occurrence time of impulse-switching moments is revealed by several …

Finite-Time Boundedness of Impulsive Delayed Reaction–Diffusion Stochastic Neural Networks

Qi Yao, Tengda Wei, Ping Tao Lin, Linshan Wang

Considering the impulsive delayed reaction-diffusion stochastic neural networks (IDRDSNNs) with hybrid impulses, the finite-time boundedness (FTB) and finite-time contractive boundedness (FTCB) are investigated in this article. First, a novel delay integral inequality is presented. By integrating this inequality with the comparison principle, …

Tracking control of wheeled mobile robots via intermittent control

Xinyi He, Xiuping Han, Tengda Wei, Xiaodi Li

This paper was concerned with the trajectory tracking control of wheeled mobile robots using aperiodic intermittent control. By establishing the corresponding motion model of the wheeled mobile robot, a tracking control strategy was proposed based on the intermittent control approach and backstepping …
