Abstract: The paper applies the RBF networ k feedforward controller combined with the proportion-feedback controller on the turntable ser vo system. In this scheme, single neuron is used to identify the system model on line,which presents t he Jacobian coefficient for t he feedforwar d controller . The simulation result on the velocity-loop indicates that the contr oller above improves tracking pr ecision and dynamic performance in low frequency signals.

Key words: feedforward control, single neuron, RBF network, turntable
