Design and Analysis of a Space Dynamic Test Platform

Abstract

This paper describes a kind of laboratory simulation test platform. The dynamic coupling model of the simulation test platform has been obtained by using the Newton-Euler equation. According to the inverse-system, the equation can be decoupled, and the decoupling analysis and calculation of the system are performed through the decoupling theorem. As a result, the coupled nonlinear Multiple-Input Multiple-Output system is converted to two linear decoupled Single-Input Single-Output subsystems. The establishment of the mathematical model can provide reference for the design of the controller in the simulation test platform. In order to verify the error of the rotation accuracy of the simulated test platform developed, a reasonable experimental scheme was developed for testing.
