STABILITY EVALUATION OF AN AIRPLANE WITH A DIGITAL MULTIRATE CONTROL SYSTEM IN A LATERAL MOTION
RESUMO
Stability margins of an airplane with a control system are analyzed for lateral motion. Different architectures of the control system are considered, namely, the analog system, the digital single-rate control system (single-channel and triplex-channel cases), and the digital multirate control system (single-channel and triplex-channel cases). The effect of interchannel data equalization on the stability margins of the closed-loop system "airplane-Fly-By-Wire (FBW) system" is analyzed. While analyzing the stability of a multiloop system, its decomposition to internal contours is used. The stability analysis of a triplex system includes cases of a failed sensor of backloop signal in one channel.
