In the proposed method, virtual measurements are treated as equality constraints, which avoids the numerical ill-conditioningproblem due to the disparity in weighting factors.
该方法把虚拟测量处理为等式约束,避免了由于权因子分散而导致的数值病态问题。

The parameter estimation problem in parameter adjustment model is considered when outliers and ill-conditioning exist simultaneously.
