Abstract: A Hopfield neural network is used as an adaptive control of the AC drive system. The dynamic output of the speed controller is programmed through neural network, so that the speed controller has a good robustness against the variation of parameters. By adding the parameter auto tracking neural networks, a double neural network adaptive programming control model with the function of on-line parameter tracking is constructed to overcome the uncontrollable load torque. Simulation results show that this system is capable of good dynamic performance.

Key words: adaptive control, controller, neural network
