摘要
温度是航空发动机运行过程中一个重要的状态参数,需准确、快速地测量。但当前航空发动机温度测量存在较大的滞后问题,致使执行机构动作不及时,导致故障的发生。为解决温度测量中的滞后问题,在分析了温度传感器数学模型的基础上,设计了合适的传感器校正方案;并进行了温度传感器校正系统的仿真。仿真计算结果表明,所采用的校正方案可明显改善温度测量系统的动态响应特性,准确、快速地跟踪被测温度。所提出的温度传感器校正算法具有适应性良好、抗干扰能力强等突出优点,为解决航空发动机温度测量问题提供重要参考。
The temperature is an important parameter in the aero-engine, and it needs to be measured accu- rately and quickly. Currently, there is a big lag problem on the temperature measuring system in the aero-engine, resulting in the actuator acts not timely, and leading to the occurrence of the fault. To resolve the problem of tem- perature measurement lag, The mathematical model of the temperature sensor is analyzed, designed a suitable sen- sor calibration scheme, and simulated the temperature sensor calibration system. The simulation results show that the calibration scheme can improve the dynamic response characteristics of the temperature measuring system signif- icantly, and track measured temperature accurately and quickly. The raised temperature sensor calibration algo- rithm has the advantages of good adaptability and strong anti-jamming capability, and provides an important refer- ence for solving the problem of temperature measurement in the aero-engine.
