Application of sampled-data control by using vibration manipulation function to suppress residual vibration of travelling crane

Vibration manipulation function (VMF) is applied as a linear-piecewise feedforward function to suppress residual vibration of a hoisting load in a one-dimensional overhead travelling crane. The system is modeled as a pendulum of a one-degree-of-freedom (1DOF) oscillator with enforced acceleration of...
