    • The present invention relates to control systems intended for use in complex technical objects that operate in a wide range of modes and loads, wherein said invention can be used in the control systems of jet engines, power-plant turbines, etc. The method of the present invention involves connecting sensors (3) to the condition monitoring units which are designed according the model of the engine (object) (1), and connecting all sensors but one to the remaining monitoring units. The method involves calculating the weighted sum of the square values of the offsets between all condition monitoring units, and comparing the values of the weighted sum of the square values of the offsets in a first unit with the values of the weighted sums of the square values of the offsets in each of the remaining monitoring units. The maximal value among the values of the difference signals obtained is compared with a threshold value and, in case said value exceeds the threshold value, a failure signal is generated for that sensor (3) whose parameters are not used in the operation monitoring unit. The method further involves determining for each monitoring unit the potential location area of the offsets due to parametering errors of the object model, and determining those monitoring units whose offsets exceed the limits of a predetermined area.
    • 本发明涉及旨在用于在宽范围的模式和负载下工作的复杂技术对象中的控制系统,其中所述发明可用于喷气发动机,电厂涡轮机等的控制系统中。 本发明涉及将传感器(3)连接到根据发动机(物体)(1)的型号设计的状态监视单元,并将所有传感器连接到其余的监视单元。 该方法包括计算所有条件监测单元之间的偏移的平方值的加权和,并将第一单元中的偏移的平方值的加权和的值与平方值的加权和的值进行比较 的每个剩余监测单位的偏移量。 将获得的差分信号的值中的最大值与阈值进行比较,并且在所述值超过阈值的情况下,对于在运行监视单元中未使用参数的传感器(3)生成故障信号。 该方法还包括由于对象模型的参数误差而确定每个监视单元的偏移的潜在位置区域,并且确定其偏移超过预定区域的限制的那些监视单元。
