INTELLIGENT IDENTIFICATION MODELING FOR SMAII-SCALE UNMANNED HELICOPTER

摘要

This paper analyses the small-scale unmanned helicopter's attitude channel dynamical characteristics and establishes a simple model structure set. The data used to identify and verify the proposed model is collected and preprocessed. Using the genetic algorithm and the data, the transfer function model structure expressed by the alterable fractional form can be gained, and the nonlinear fuzzy model is attained using the T-S fuzzy rules and the proposed transfer function model structure. The identified results indicate that the resulted model is accurately enough. The resulted model expresses the characteristics of the attitude channel and is useful to design the control system and analyze the helicopter.
