中文说明：基于RBF神经网络整定的PID控制径向基函数具有单隐居的三层前馈网络。是—种局部逼近网络，己证明它能以任意精度逼近杠意连续函数。
English Description：
The radial basis function of PID control based on RBF neural network tuning has a single recluse three-layer feedforward network. It has been proved that it can approximate continuous functions with arbitrary precision.
