摘要

信号微分在系统监控中有着广泛的应用。微分器设计的关键问题是如何在微分精度和对不确定性和噪声的鲁棒性之间取得满意的平衡。在提出一种新的二阶积分器链有限时间稳定器的基础上，提出了一种信号及其导数估计误差均有界的二阶微分器。然后应用该微分器来估计核反应堆中子通量的导数。数值模拟结果不仅验证了理论结果，而且表明了该微分器的良好性能。

A two-order finite-time-convergent differentiator with application to nuclear reactors

Signal differentiation is widely used in system monitoring and control. The key problem in differentiator design is how to obtain a satisfactory tradeoff between differentiation exactness and robustness to uncertainties and noises. Based upon proposing a novel finite-time stabilizer for 2-order integrator chain, a new finite-time-convergent 2-order differentiator with bounded estimation error of both the signal and its derivatives is newly developed. This differentiator is then applied to estimate the derivative of the neutron flux of nuclear reactors. Numerical simulation results not only verify the theoretical results but also show the satisfactory performance of this newly-built differentiator.
