Abstract

The basic problem in designing control systems is the ability to achieve good performance in the presence of uncertainties such as output disturbances, measurement noise or unmodeled dynamics (i.e. robust controllers). Recent development in the area has been directed towards developing a consistent design methodology within this uncertain environment. The attitude control/ momentum management of the space station poses a typical problem in a highly uncertain environment (such as mass properties of the Space Station and environmental disturbances as well as parametric uncertainties). The objective of this research is to use LQR control for the position control of spin axis rotor position at reference value in the presence of parametric uncertainties, external unmeasurable disturbances and system inherent non-linearity with different type’s reference tracking signal are considered extensively in this paper.
