GA-Based Evolutionary Identification of Model Structure for Small-scale Robot Helicopter System

摘要

This paper analyses problems in the model identification and express the transfer characteristics of small-scale robot helicopter using the fractional form. Subsequently, a GA-based identification method is used to identify it. Our proposed method is verified through an example and an experimental study. The example can see that the genetic algorithm used to identify the transfer function is useful and feasible. The experimental results reveal the robot helicopter system structure and the identification of parameters can be simultaneously attained using the proposed GA method, in contrastto the conventional identification algorithms.
