Description
Summary:and attitude rate are determined from the space
and torque bias are developed. This advisory system
based advisory system for detecting off-nominal
behavior of spacecraft digital autopilots(DAP) in
can be used either for simulations on the ground or
for onboard use by astronauts. It can also accept
off-nominal behavior such as chattering, overshoot,
real-time. The DAP of the space shuttle is used as a
required, by the phase plane switching logic and jet
selection logic. Rules-based methods for detecting
shuttle dynamic model, and the control torque
significant deviations are observed between
simulation model for this study. Errors in attitude
simulations and the actual behavior of the DAP.
