中文摘要: 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.
Abstract: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 Matlab simulation experiment show that the estimation accuracy is improved.
