    Abstract: In this paper, a combinational control approach of sliding mode-PID is utilized in free floating space manipulator. Due to float base, nonlinearity of free floating space manipulator dynamics lead to having unstable behaviour and complicated dynamic model. To simplify the dynamic equation, dynamically equivalent manipulator is utilized which is a f... Show More

    Abstract: This paper examines the adequacy of first order shear deformation theory (FSDT) based layered shell finite element by comparing with 2D and 3D models without imposing any constraint on the deformation behaviour of core. The effect of core compressibility and transverse flexibility in the behaviour of sandwich beams are studied. Plane and 3D models ... Show More
