摘要
随着现代科学技术的发展,各种类型的自动控制系统得到了广泛应用,与此同时,控制系统的可靠性问题也引起了极大的重视。根据残差信号的特点,综合了几种阈值选取的原则,并分析了求取阈值最优值的方法。给出的方法具有一定的准确性,可以在生产实际中作为参考。
With the development of modern science technology,automatic control system has been widely applied and the reliability of control system has been taken seriously. According to characteristic of residual signal ,optimum value of threshold is gained with analysis method after fundamental rule of threshold selection is synthesized. Method given in this paper is accurate to the extent and it can be used in production practice.
