基于改进遗传算法的空间桁架结构振动传感器/作动器布局优化研究
Optimal Placement of Vibration Sensors and Actuators in Space Truss Structures with an Improved Genetic Algorithm
摘要
Abstract
In this paper,an improved genetic algorithm based on mesh coordinates is proposed to address the sensor/actuator placement optimization problem for vibration control in large space truss structures.This approach effectively resolves the decoupling issue between nodal sequence and actual spatial positions through a binary mesh coordinate-based encoding scheme,while significantly enhancing the search efficiency by incorporating an elitist preservation strategy.The simulation experiments conducted on a large space truss structure demonstrate that the proposed algorithm accelerates the convergence process while improving the fitness values,exhibiting superior search efficiency and stability.The research results provide reliable technical support for vibration control in large space structures.关键词
