abstract

  • A study aims to develop and study the stability of an optimal hybrid control scheme in which magnetic torquers and impulsive thrusters work in tandem and in an optimal manner, as they are designed using the so-called hybrid LQR approach. The design approach uses impulsive thrusting to complement the magnetic controller to overcome the aforementioned gain limitation issues associated with a continuous feedback controller. The study also aims to optimize the two actuation control inputs to be used together.
