具有区域极点约束的无偏H_∞滤波

The Unbiased H_∞ Filtering with the Pole Constraint

本文在无偏估计存在的条件下,给出了具有区域极点约束的无偏H∞滤波器的设计方法。该方法克服了传统滤波方法的局限性,既考虑了系统的输入输出鲁棒性能,也考虑了内部动态性能的要求,同时简化了滤波器的设计过程。以对河流污染物B.O.D含量的估计为例,仿真结果表明本方法具有较好的估计效果。

Under the unbiased condition, the design of the unbiased filter with the pole constraint is given. This method overcomes the limitations of classical filtering. It considers the robust performance of input and output, also the inner dynamic performance. And the unbiased H filtering approach simplifies the design processing. Using estimation for the B.O.D of the polluted river as the example, and results of simulation show this approach has a better estimation effect.
