A New Performance Optimization Method for Linear Motor Feeding System

چکیده
The linear motor feeding system is a typical electromechanical coupling system. Conventional characteristic analyses of often overlook the influence flexible deformation in critical components Moreover, when employing genetic algorithms to optimize servo PID control parameters, slow convergence, nonconvergence, or premature convergence problems may arise. To address these issues, this paper proposes new performance optimization method for uses combination “multi-body theory + finite element” accurately account system, establishes rigid–flexible model and optimizes parameters established with an improved adaptive algorithm. Simulation results demonstrate that, utilizing algorithm that disregards body deformation, achieves stability 0.02 s 0.027 overshoots 13% 27%, respectively. These outcomes confirm accuracy importance considering At same time, time required reach steady state optimized by shortened from 0.035 s. sinusoidal signal response curve does not exhibit any peak overshoot compared nonoptimized speed also faster. effectiveness nonlinear displacement curves under different workbench loads are obtained through experiments those simulations verify correctness proposed method.

A New Two-Stage Method for Damage Identification in Linear-Shaped Structures Via Grey System Theory and Optimization Algorithm
The main objective of this paper is concentrated on presenting a new two-stage method for damage localization and quantification in the linear-shaped structures. A linear-shaped structure is defined as a structure in which all elements are arranged only on a straight line. At the first stage, by employing Grey System Theory (GST) and diagonal members of the Generalized Flexibility Matrix (GFM),...
