Subspace Model Identification Methods for Identifying the Small-scale Unmanned Helicopter Dynamics

Because most multivariable control methods are model-based, and the dynamic model for a particular small-scale helicopter which is simple enough to be practical for controller is not readily available, the identification of small-scale helicopter´s dynamic model is a necessary part of any model-based control design. This paper describes the MO ESP method which uses numerically robust computation tools applied in the model identification of a small-scale helicopter dynamics. The result of simulation shows this method is suitable for the dynamic identification of a small-scale helicopter.
