Abstract This paper presents an experimental study on wrinkle reduction in a rectangular membrane structure with elliptical boundary cuts. The structure is subjected to two different heat loads: 145°C and 205°C. Wrinkling induced by the thermal expansion of the membrane is measured using a photogrammetry system and the root mean square of the membrane's surface above a plane of best fit. A fuzzy logic controller is developed to track a desired flatness level when the membrane is subject to either application or removal of a thermal load. Experimental verification is conducted using a membrane structure test facility and the results show that wrinkles have been reduced significantly and quickly using the proposed fuzzy logic controller.
Highlights ► We perform experiments on a space rectangular membrane structure. ► The membrane is subjected to a varying thermal load creating flatness deviations. ► We design and implement a fuzzy logic controller for active flatness control. ► The controller enables a desired flatness level for the membrane to be tracked.
