Abstract

Two methods are presented to design joint trajectory for a two-link flexible manipulator. In the first one, a combined Fourier series and polynomial function are used and in the second, a B-spline function is considered. In both the cases, the path satisfies the start and end kinematic constraints of motion. Using energy approach for the above two cases, the final path is generated optimizing kinetic and strain energy at the goal point that reduces the residual vibration significantly. The present study is to compare the two methods and to predict that the B-spline curve has faster convergence property and at the same time, minimizes the performance index by six-fold and hence, the reduction of residual vibration is also more as compared to the combined Fourier series and polynomial function. The dynamics of the manipulator arm during its motion as well as free vibration after reaching the goal are described by finite element analysis using Lagrange's equation of motion.
