本文简述了余度技术中的模型监控,介绍了籍助于模拟技术确定模型监控中各参数的方法,所得的参数——安全门限值和延迟电路的时间常数可作设计比较器的依据。文内还提出了设计舵迥路电子模型的方法以及一种可实现的电子模型方案,最后指出了减小误切除概率的途径。 In this paper, the model monitoring in redundancy technology is briefly introduced. The method of determining the parameters in the model monitoring by means of simulation technology is introduced. The obtained parameters - the safety threshold and the time constant of the delay circuit can be used as the basis for designing the comparator. In the paper, a method of designing the electronic model of rudder path and a realizable electronic model scheme are put forward. Finally, the ways of reducing the probability of false excision are pointed out.
