Abstract:

The design of spacecraft servo mechanism plays an important role in the control of the spacecraft. The research of control algorithm and the construction of simulation platform have important practical value. This paper modelles and simulates the mechanical, electrical, hydraulic parts of the aerospace servo mechanism. The overall model of the whole servo system is established. The mechanical structure of the servo mechanism is built in ADAMS and the hydraulic module is built by AMESim. Based on H theory, the robust controller is built with Matlab toolbox. Combined with the dynamics model of ADAMS and AMESim, as well as the Matlab controller model, the joint simulation of each module is realized. Through the joint simulation technology, the simulation of physical system is more realistic, and the experimental results are also displayed more intuitively. This simulation has a good guiding significance for the design and construction of actual spacecraft servo mechanism system.

Key words: joint simulation, servo mechanism, mechanical-electrical-hydraulic integration, robust con-trol, spacecraft
