Study on Intelligent Deployable Control of the Space Extensible Antenna Based on Neural Network

The deployable dynamic equation of the Hoop Truss Deployable Antenna(HTDA) was setted up in flexible multi-contact system dynamics.According to non-linearity and character varied from time during outspread process of HTDA,intelligent control system with forecast and optimization in time for system state was designed based on neural network,which gives intelligent control approach for outspread process velocity.The simulation result shows that such kind of control method can effectively resolve non-linearity and uncertainty of the multi-variable control system as space extensible antenna,and perform very well in control accuracy,stability,adaptability and robustness.
