This research investigated hybrid control strategies for rapid
satellite pointing. First, a detailed computer simulation model of
AFIT's SIMSAT satellite simulator was constructed. Control
strategies were developed to enable the system to perform
large-angle, 3-axis slewing maneuvers using a combination of both
thrusters and reaction wheels. To handle the non-linear model, a
State Dependent Riccati Equation controller was programmed and
successfully controlled the computer-modeled satellite for any
given slewing maneuver. A simpler PD controller was then programmed
and demonstrated on the computer simulation of SIMSAT, using a
combination of thruster and reaction wheel control inputs for
large-angle single axis maneuvers and for small angles using
three-axis control. There was good agreement between the
experimentally obtained maneuver results and those produced with
the computer simulation model for the single-axis case. Lastly, the
trade-off between settling time and thruster fuel is discussed, as
well as the variation of gains required to achieve maximum
performance for a desired slew.
