Considering the big influence of load disturbance, model parameter uncertainty and nonlinear factors,a single-neuron adaptive PSD controller is designed and studied. Based on the self-learning and self-organizing ability of the neuron, the weight of the plant is adjusted online.Furthermore, the algorithm of self-regulating the gain is given.Meanwhile,the speed of the PSD algorithm is improved. The simulation results show that the adaptive PSD servo-controller has a good performance.
