【Abstract】 In this paper, Hopfield Neural Network (HNN) is introduced into adaptive control of AC drive system, in which the dynamics of its speed controller is set by HNN programming result, thus making the speed control result robust to some parameters’ changing. As to the uncontrollable load torque part, the adaptive parameters’ tracking HNN is added into the system to make out the dual-HNN based adaptive AC drive system programming tracking control mode, thus improving the control performance of the system. These results are proved by simulation.更多还原
