| Abstract: | The Paper proposes 3D ultra-micropositioning mechanism,which is composed of flexible hinge mechanism and piezoelectric actuator.The non-linearity characteristics and dynamic characteristics of ultra-micropositioning mechanism are analyzed in theory and studied by experiment.To meet the need of high-precision positioning,a digital PID feedback controller is adopted to improve the performance of the ultra-micropositioning system.Finally,this system is used in manipulator. |
