摘要:

基于压差比的迎角侧滑角传感器是一套独立的智能测试系统,没有内在的摩擦、迟滞和过冲,测量范围更大、精度更高,但孔径细小易发生堵塞。为提高压差比迎角侧滑角传感器用于飞行试验的可靠性,文中针对五孔探头压差比迎角侧滑角传感器(简称五孔探头)展开容错机制研究,该容错机制直接采用五孔探头测量数据,具有计算效率高、时延小等优点。首先提出容错的校准系数定义方法,并探讨该定义下迎角侧滑角解算时解的唯一性问题。然后,分析不同故障情况下的容错校准系数选择策略,给出容错机制下的迎角侧滑角解算算法。最后,通过试验表明迎角侧滑角的解算误差最大不超过0.2°,验证所提容错机制的合理性和可行性。

Abstract: The angle of attack and sideslip sensor based on the differential pressure ratio is an independent and intelligent test system, without inherent friction, hysteresis and overshoot, leading to larger measurement range and higher measurement accuracy, but the small orifices are prone to blockage. In order to improve the reliability of the angle of attack and sideslip sensor based on the differential pressure ratio for flight test, the paper focuses on the fault-tolerant mechanism study of the angle of attack and sideslip sensor based on the differential pressure ratio, which is equipped with a five-hole pressure measurement probe(hereinafter referred to as five-hole probe). The fault-tolerant mechanism directly uses the measurement data of the five-hole probe, maintaining the advantages of high calculation efficiency and small time delay. First, the definition method of the fault-tolerant calibration coefficients is proposed, and the uniqueness of the solution when calculating the angle of attack and sideslip under this definition is discussed. Then, the selection strategy of the fault-tolerant calibration coefficients under different fault conditions is analyzed, and a fault-tolerant calculation algorithm for angle of attack and sideslip is given. Finally, experiments show that the maximum error of the angle of attack and sideslip does not exceed 0.2°, which verifies the rationality and feasibility of the proposed fault-tolerant mechanism.
