摘要

Real time monitoring of the control system of a Boeing 747 aircraft (B747) is considered by using a pulse-compression probing method. The method extracts small signal characteristics of the targeted system, and detects deviations from the system's normal behavior with high sensitivity. This thesis demonstrates, through a simulated model of a B747 longitudinal motion, the successful application of the probing method in monitoring a nonlinear dynamic system. The first part of the thesis shows the process of determining suitable probing signals and probing structure for the B747, and discusses the monitoring results for two major types of faults in its actuators. It focuses on validating the effectiveness of the probing method in monitoring nonlinear systems based on the model of the longitudinal motion of B747. The second part of the thesis documents the effort of hardware implementation of the probing algorithm using a field programmable field array (FPGA).
