Method of System Identification Based on PSO Algorithm

A novel method was studied for system identification based on particle swarm optimization(PSO) algorithm. The basic idea of the method employs a system model composed with classical models so as to transform the system structure identification problem into a combinational optimization problem. A PSO algorithm is then adopted to implement the identification on the system structure and parameters. Finally,simulation results show the rationality and effectiveness of the presented new method,and that the new method has high identification accuracy and very practical.
