Automatic flight control computer signal MATLAB simulation test device and test method

The invention relates to the technical field of airborne automatic flight control computer testing, in particular to an automatic flight control computer signal MATLAB simulation testing device and method. The industrial computer is arranged in the cabinet; the display, the keyboard and the mouse are arranged in the cabinet, and the display, the keyboard and the mouse are matched with the industrial computer; the system comprises a double-path direct-current stabilized power supply, a signal conditioning case, a control panel and a junction box. The functions of switching of different states of a product, input of initial parameters, collection of bus data, automatic flight control signal simulation and the like can be achieved. On-line parameter adjustment can be realized, test and automatic flight control signal output results can be checked in real time, the air state can be simulated, the flight process can be reproduced, and the method is used for air fault analysis. Dynamic excitation testing is adopted
