Abstract


In this paper, the future space warfare research background to China's future mobile platforms and weapon load space as the research object , using nonlinear disturbance rejection control technology, the mobile platform space station body attitude control, tracking and pointing weapons load control platform attitude maneuver and weapons payload pointing composite control in-depth and meticulous research . Firstly, using the Lagrange equation established space station body dynamics equations mobile platforms and weapons load point kinetic equation for space maneuvering platform simplified kinetic models , the first double-loop platform designed ADRC attitude control system , the self- anti- Rejection Controller design is almost does not depend on the specific dynamics model mobile platform to achieve attitude control only control input influence matrix estimate without accurate dynamic model platform , from engineering point of view, this double-loop platform ADRC attitude control system simulation under a variety of conditions . Verified by simulation mobile platform attitude ADRC has strong anti-interference and a wider range of applicability . ADRC Tracking Differentiator theory, combined with weapons load operating mode and pointing strategy, design loads of weapons outside the ring pointing ADRC control system. Gives a different weapon load tracking operation mode tracking differentiator parameter selection method , based on this , and in front of the attitude control system design together form a space for mobile platforms and weapons load platform body gesture tracking and pointing two control complex control system and the composite control system simulation. Simulation results show that the composite three-channel controller can achieve decoupling control gesture , pointing to two -channel decoupling control, pointing to the load platform body posture decoupling . Improve the control efficiency for space maneuvering platform control system control precision and control efficiency requirements , indicating ADRC is designed to meet the complex maneuver controller platform and payload pointing weapons complex control system requirements .
