Abstract
A neural-network control concept is introduced for
structurally flexible robotic manipulators. The control architecture
is based on Albus's Cerebellar Model Arithmetic
Computer (CMAC) The scheme employs Jordan's supervised
learning technique with a distal teacher. The resulting control
architecture is the Forward-Inverse CMAC, or FICMAC for
short. A forward-dynamics module of the robotic system
is used to train an inverse-dynamics module that provides
control torques to the system. The technique is suitable for
on-line learning and moreover, as a numerical example illustrates,
learning can be achieved in a relatively few trials.
