Comparative Study on the Spacecraft Attitude Control Methods: Traditional and Intelligent Methods

Abstract

In response to the issues of spacecraft attitude control, this paper comprehensively analyzes the principles, advantages, disadvantages, and application cases of spacecraft attitude control from the perspectives of traditional control design methods and intelligent control design methods, and discusses the current development trends of spacecraft attitude controllers. An overview of the current development and prospects of control methods such as PID control, sliding mode control, fuzzy control, neural networks, etc. is provided. It is found that the traditional controller mainly solves relatively simple control problems such as linear and time-invariant, and it is not easy to adjust parameters. The intelligent controller relies on its algorithm and it simplifies the process of parameter adjustment, has strong adaptability, and can face unpredictable environments. Therefore, spacecraft attitude control will play an increasingly important role in the future.
