| Abstract: | In order to control the elastic vibration and improve the position accuracy of the flexible manipulator,the dynamic model of a single-link flexible manipulator has been derived and linearly parameterized.We apply the linear quadratic regulator to control the tip vibration of the flexible manipulator based on the model.Simulation results illustrates that the tip vibration is significantly suppressed. |
