Abstract:

Balanced truncation method is employed to investigate the problem of model reduction on multi input/multi output system. The process of low order modeling on ASE system is given in brief. The principle and algorithm of balanced truncation method are discussed in detail. The ASE system for a wing model is applied to reveal the mechanism of the method by comparing the full model with the reduced order model.

Key words: aeroelastic, aeroservoelastic, model reduction, balanced truncation
