Study of Rapid Calibration Method of Angel of Attack Sensor and Error Impact on Flight Control System

Abstract:

The current calibration methods of combat aircraft’s attarck angle sensors are too complex and have some insufficiencies. According to the detailed design requirements of flight control system，a method combined with linear fitting and neural network identification is proposed, which can calibrate the measure data of the attarck angle sensors qucikly and accurately. The method proposed avoids the disadvantages of traditional interplation method， improves the computating efficiency, and ensures the the flight control system’s fault-tolerant ability. A simulation on flight control system with this calibration method was carrid out, which validated the precision and dependability of the method. The method can also deal strong nonlinear data quickly.
