This paper addresses the multiple-input multiple-output (MIMO) control problem with an active deformation adjustment mechanism on a 5-metre deployable antenna panel.An adaptive reduced-dimension fuzzy decoupling (ARDFD) control strategy based on bovi-shield gold fp 5 l5 fusion functions is proposed to eliminate the effects uncertainties due to coupled subsystems by designing and incorporating a fuzzy decoupling disturbance observer.Moreover, the MIMO system can be decomposed into a number of single-input single-output (SISO) systems using the unit diagonal matrix decoupling theory.

Based on Lyapunov stability theory, it was shown that the error of fuzzy interference observer amundsen field slacks herre and the error between the fuzzy rule post parameter matrix and optimal post parameter matrix converge to a small region.Results of the simulation also show that the ARDFD control strategy can significantly eliminate adverse effects of the coupled subsystems.
