| With the technical development of Satellite Multiple-beam Antenna, therequirement of multiple-beam antenna pointing controller and pointing controlprecision of antenna is increasing gradually. In order to shorten the time of design anddebugging of multiple-beam antenna pointing controller, and improve the performanceof control system, the simulation of multiple-beam antenna pointing control systemwas carried out，and the design of the system is described in the paper.The paper is consist of four parts. First of all, the function and working modes ofthe multiple-beam antenna pointing control system antenna control system aredescribed, and the system structure and function are introduced. Subsequently, themathematical models of the antenna, the tracking receiver, the controller, thetwo-phase hybrid stepper motor, the motor driver and the harmonic driver reducer arededuced. Based on the mathematical models, the system simulation model is built byMatlab/Simulink software, and the model performance is analyzed.At last，based onthe model, the realization of the system is described in the paper，Some keytechnologies of them are depicted on hardware and software.The effective of the Multiple-beam Antenna Control System is showed by the testresults. |
