This paper will present results of applying two autonomous fuzzy contr
ollers to a dynamically coupled system. The system consists of a space
platform and a gimballed payload. The controllers are developed with
the systems decoupled. Parametric studies are performed on the support
limits for the error, change-in-error, and control. These parametric
variations provide insight into satisfactorily tuning the controllers.
The controllers were compared to controllers developed using Linear Q
uadratic Regulator (LQR) control design. The controllers are used to p
erform slew maneuvers and disturbance rejection. A design procedure us
ing constraints due to hardware or software specification is also exam
ined. When error and control support limits are specified, tuning the
fuzzy controller is made relatively easy. The systems were coupled and
the response of the payload and platform were examined for commanded
payload trajectories and impulses applied to the platform. The fuzzy c
ontrollers performed very well in all cases.
