Parameter Adjustment of the Autothrust Control Law by Flight Tests

Abstract Aiming at deriving precise automatic control of airspeed, a comprehensive flight test solution for autothrust law parameter adjustment was proposed, providing worthy reference other aircraft types’ work, including the points and methods, modification requirements test, system performance analysis evaluation risk analysis. A method invoking scripts by interface unit panel to configure parameters input excitation signals proposed first time. The devices cross-link can be fully verified in advance both iron bird real ground tests, which greatly reduce unexpected risks based on engineers’ personal experience. According from three aspects response, robustness throttle lever movement data, optimal configuration given.
