【摘要】:针对含状态时滞的线性离散时变状态空间模型,提出一类无偏有限脉冲响应(UFIR)滤波算法.通过构造含有时滞状态的增广系统模型,对原系统进行无时滞转换.利用扩展状态空间模型的思路,将现有UFIR滤波算法推广至含控制输入的状态时滞系统中,并进一步求解相应的迭代形式,保留类Kalman算法快速计算的特点.通过仿真例子表明了所提出算法的有效性.
[Abstract]:A class of unbiased finite impulse response UFIRs filtering algorithm is proposed for linear discrete time-varying state space model with state delay.By constructing an extended system model with time-delay state, the delay-free transformation of the original system is carried out.Based on the idea of extended state space model, the existing UFIR filtering algorithm is extended to the state delay system with control input, and the corresponding iterative form is solved further, which preserves the characteristics of fast computation of the similar Kalman algorithm.A simulation example shows the effectiveness of the proposed algorithm.
