System Identification of Heat-Transfer Process of Frequency Induction Furnace for Melting Copper Based on Particle Swarm Algorithm

Abstract EN

An adaptive evolutionary strategy in standard particle swarm optimization is introduced.

Adaptive evolution particle swarm optimization is constructed to improve the capacity of global search.

A method based on adaptive evolution particle swarm optimization for identification of continuous system with time delay is proposed.

The basic idea is that the identification of continuous system with time delay is converted to an optimization of continuous nonlinear function.

The adaptive evolution particle swarm optimization is utilized to find an optimal solution of continuous nonlinear function.

Convergence conditions are given by the convergence analysis based on discrete time linear dynamic system theory.

Numerical simulation results show that the proposed method is effective for a general continuous system with time delay and the system of heat-transfer process of frequency induction furnace for melting copper.
