The optimum keep watch over of versatile buildings is an lively zone of analysis. the most physique of labor during this quarter is anxious with the keep watch over of time-dependent displacements and stresses, and assumes linear elastic stipulations, specifically linear elastic fabric habit and small defor- tion. See, e. g. , [1]–[3], the collections of papers [4, 5], and references therein. nonetheless, within the current paper we reflect on the static optimum regulate of a constitution made from a nonlinear elastic fabric and und- going huge deformation. a huge software is the suppression of static or quasi-static elastic deformation in versatile house buildings resembling elements of satellites by means of regulate rather a lot [6]. sun rad- tion and radiation from different assets set off a temperature box within the constitution, which in flip generates an elastic displacement box. The displacements needs to often fulfill sure boundaries dictated by way of the allowed operating stipulations of varied orientation-sensitive tools and antennas within the area motor vehicle. for instance, a parabolic reflector may well stop to be potent whilst present process huge deflection. The elastic deformation could be lowered by way of use of keep an eye on so much, that could be imp- mented through mechanically-based actuators or extra sleek piezoelectric units. while the constitution into consideration is made from a rubb- like fabric and is present process huge deformation, nonlinear fabric and geometric results needs to be taken into consideration within the analysis.
