| 摘 要： | 根据衰减记忆因子为一个常数的不尽合理性的假设,深入研究了指数加权衰减记忆滤波因子,根据滤波收敛条件和滤波模型准确时的新息(残差)特点,提出了具有自适应性、抑制滤波发散的指数加权衰减记忆滤波算法,并通过仿真试验验证了自适应抑制滤波发散的有效性。

| Abstract: | According to the irrational hypothesis problem that the fading memory factor is constant, exponential weighting factor is discussed in this paper. Based on filter convergent condition and characteristic when the model is exactness, put forward an algorithm of adaptive exponential weighting fading memory filter to prevent filter divergence. Simulation results show that this algorithm is effective. |
