| 摘 要： | 推导了参数平差模型序贯平差在参数可变情形下的Ｍ－Ｍ抗差及Ｍ－ＬＳ抗差解式，讨论了相应的影响函数及验后协方差。固定参数序贯平差抗差解为其特例。模拟计算表明，抗差序贯平差能有效地抵制粗差干扰。

| Abstract: | A general Robust sequential estimation with variable parameters is put forward,and, the error influence functions and the posterior covariance are derived.Some special cases under particular assumptions are discussed.An example is given to show that Robust sequential estimation can effectively control the influnces of the outliers. |
