Abstract: PURPOSE:To obtain a highly accurate nonlinear system learning device by securing a hierarchical combination of multi-layer learning neural circuits which change the synapse weighting by a feedback loop and a feedback command. CONSTITUTION:The target track signals thetad1-thetadN are added with the feedback signals theta1-thetaN of a feedback loop 3 via a subtraction circuit 1.

An addition circuit applies the torques Tf1-TfN and Ti1-TiN to a manipulator 5 and outputs the actual tracks theta1-thetaN to feed them back to a subtraction circuit via a loop 3. In addition, the torques Tf1-TfN are also given to the output layer of the circuit 7 as error signals. Then a track approximately coincident with a target is obtained at the final learning stage.
