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.
