In cousideration of the nonlinearity and time variation of the dynamic model in the process of the antenna outspreading, based on neural network, the paper designed a process control system that has the functions of forecast and real-time optimization, providing an intelligent control method for extensible antenna outspreading process velocity. The intelligent control method can resolve nonlinearity, multi-variables and time variation control in the outspreading process of space extensible antemas and has good performance in control accuracy, adaptability, stability and robustness.
