| 6. | With the development of signal processing techniques and fast algorithms , the signal detection theory got much progress . generally speaking , robust detection methods can be divided into two major branches , classical methods which are based on robust hypothesis testing and modern methods based on new signal processing methods 同时信号处理方法和计算机以及快速计算技术的快速发展大大丰富了信号检测的手段,可以在原来理想模型的基础上进行鲁棒化( robustification ) ,或者采用新的检测方法。 |
| 7. | Since the western countries began the srfcs research in the eighties , theory of signal detection is used in fdi , and it was successful in some fdi functions in several types of testing aircraft . china did the srfcs research recently , but lack of the engineering fdi algorithm . because the " model based signal detection algorithm " is sensitive to the matching accuracy of the mathematics model and aircraft has prominent nonlinear aerodynamic factors , it is difficulty to upgrade the ability of fdi based on the classical signal detection theory and data fusion only 国外自八十年代开展自修复研究,一般采用基于常规数据处理的故障检测理论来实现飞控系统故障检测与隔离功能,现已在几种验证机上取得初步成果,而国内的研究尚缺乏实用的工程算法;同时,基于常规数据处理的故障检测精度对被检测对象的数学模型匹配度敏感,且飞机的气动特性在故障情况下又具有较强的非线性特性,因此,单纯依靠常规的信号处理算法难以进一步提高故障检测的精度。 |
