| Summary: | The success of model-based
ight control law design for autonomous helicopter is
largely dependent on the availability of reliable model of the system. Considering the complexity of
the helicopter dynamics, and inherent di�culty involves with physical measurement of the system
parameters, the grey modeling approach which involves the development of parameterized model from
�rst principles and estimation of these parameters using system identi�cation (sysID) technique has
been proposed in the literatures. Prediction Error Modeling (PEM) algorithm has been identi�ed
as an e�ective system identi�cation technique. However, application of this method to complex
system like helicopter is not a trivial exercise due to inherent coupling in the system states and
the challenges associated with parameter initialization in PEM algorithm. In this work, an e�ective
procedure in application of PEM algorithm available in MATLAB toolbox is presented for small scale
helicopter using real-time
ight data. The approach was able to yield satisfactory model suitable for
model-based
ight control design. |
