摘要
介绍了基于等效电流量测变换的状态估计算法,并在此基础上提出了一种改进算法.应用抗差估计的理论构造了一组权函数,在每次迭代的过程中对权重不断修改,从而达到提高估计精度的目的.Matlab仿真实验结果表明,估计精度得到了提高.
A state estimation method based on equivalent current measurement transformation is introduced. On this basis an improved method is proposed. A set of weight function is constructed by using robust estimation theory. In each iterative process the weight is continuously changing to improve estimation accuracy. Results of M atlab simulation experiment showthat the estimation accuracy is improved.
