Abstract

In order to improve the accuracy of simulation for 3 axes servo revolution pedestal system (TARPS), stability analysis of the system is carried out. In view of integration of the mechanical structure and servo control subsystem, this paper describes the foundation and assembly of modal equations for dynamical substructures, connectors, and servo controller of TARPS. This study evaluates the influence function from the mechanical aspect and servo control aspect, and points out ways of improving dynamical stability of TARPS. This paper details mechanical structural finite element models, servo control mathematical models, and coupling between the mechanical structure and servo controller, the overall design develops through an iterative process based on trade-off between the mechanical subsystem and the servo controller.
