| Abstract: | Intelligent control scheme in view of engineering for flexible space structure was studied such as satellites with solar arrays.According to the requirement of high precision,intelligent control law composed of CMAC neural network and VSC with very simple algorithm and strong robustness was designed.With a physical simulation system based on a single axis air bearing table,the control scheme was realized successfully and high precision attitude was obtained.Results show that the method proposed in this paper is effective. |
