Lattice piecewise affine approximation of explicit model predictive control with application to satellite attitude control

no code implementations20 Mar 2024 Zhengqi Xu, Jun Xu, Ai-Guo Wu, Shuning Wang

Satellite attitude cotrol is a crucial part of aerospace technology, and model predictive control(MPC) is one of the most promising controllers in this area, which will be less effective if real-time online optimization can not be achieved.
