Abstract

We investigate the issue of vibration suppression and boundary control for nonlinear flexible rotating manipulator (FRM) in three-dimensional (3D) space subject to output restrictions. Considering partial differential equations (PDEs) model, we devise a boundary control approach to suppress distributed elastic deformation and vibration, to ensure the base and link reaches the desired angle. Barrier Lyapunov function (BLF) is applied to keep the output signal within a safe and adjustable range. Finally, we perform digital simulation to verify the validity of the designed control strategy.
