Abstract:The negative impulse input shaper was designed to implement the accurate and rapid responses to the system motion. A 3-DOF parallel manipulator system was thus introduced, as well as the system model and its dynamic equations. With the architectures of the ZV, ZVD and EI input shapers involving negative impulses given and applied to the 3-DOF manipulator system, the negative impulse input shaper was investigated in view of decreasing the time delay of the system response and its robustness and in comparison with the positive impulse input shapers. The simulation results showed that the negative impulse input shaper can suppress the residual vibration and, at the same time, decrease the time delay of the system response.
