This paper presents a proposal for a minimum energy feedforward control technique for
flexible structures to suppress residual vibrations in point-to-point (PTP) motion. In the
proposed method, the trajectory profile of the PTP motion is generated through a cycloidal
function whose input is the output of a polynomial function. The obtained trajectory is
dependent upon the coefficients of the polynomial function. To achieve the suppression of
the residual vibration as well as the operating energy of this PTP motion, the coefficients are
tuned by metaheuristic algorithms. In the numerical simulations, we investigated the PTP
motions of a single-link flexible manipulator and a robotic arm attached to a flexible link.
The simulation results were compared with those of previous studies, revealing the
effectiveness of the proposed method
