摘要

Inflatable space structures need to maintain in a desired shape in space in order to achieve satisfactory performance. The active shape control technique has shown its advantages in solving this problem. One difficulty to realize an active control system in space is how to measure the shape of inflatable structures. This paper proposes a neural network scheme to estimate the shape of inflatable structures, instead of performing measurements directly. A radial basis function neural network is trained on the ground to map environment information and control variables into the structure shape. After the neural network training completes, an estimation of the structure shape can be obtained by inputting the measured environment data and control variables to the neural network. Some validation studies have been conducted in laboratory on the estimation of the flatness of a rectangular Kapton membrane. The results showed the proposed scheme gave very good estimations of the membrane flatness.
