A Particle Swarm Optimization Algorithm with Sigmoid Increasing Inertia Weight for Structural Damage Identification

In this study, a particle swarm optimization with sigmoid increasing inertia weight (SIPSO) algorithm is proposed for structural damage identification based on the of vibration response constraints. view existing problems algorithms used identification, such as low accuracy and easy misjudgment location, introduced to improve global local search ability algorithm. Simulation results show that parameters have significant effect performance SIPSO identification. Compared similar improved algorithms, has some advantages fast convergence speed, high accuracy, strong robustness in
