Summary: | This paper presents an investigation into the development of parametric and non-parametric approaches for
dynamic modelling of a flexible manipulator system. The least mean
squares, recursive least squares and genetic algorithms are used to
obtain linear parametric models of the system. Moreover, non-parametric models
of the system are developed using a non-linear AutoRegressive process
with eXogeneous input model structure with multi-layered perceptron and radial
basis function neural networks. The system is in each case
modelled from the input torque to hub-angle, hub-velocity and end-point
acceleration outputs. The models are validated using several validation tests.
Finally, a comparative assessment of the approaches used is presented
and discussed in terms of accuracy, efficiency and estimation of
the vibration modes of the system. |
