摘要

在本文中，我们引入了一种新的混合最小二乘（MLSs）算法来处理同时估计参数/状态和未知输入的问题。首先，推导出估计期望参数和未知输入的MLSs算法，该算法可以看作是确定性最小二乘和随机最小二乘的统一框架；进一步验证了mls估计器的无偏性和最优性。在此基础上，给出了一种求解同时状态和未知输入估计问题的新方法。该方法比现有的SUIE算法更简洁、直观。本文提供的方法为未知输入的参数/状态估计提供了新的见解。

A Novel Mixture Least Squares Approach for Simultaneous Parameter/State and Unknown Input Estimation

In this article, we introduce a novel mixture least squares (MLSs) algorithm to deal with the problems of simultaneous parameter/state and unknown input estimation. First, the MLSs algorithm is derived to estimate the desired parameter and unknown input, which can be regarded as a unified framework for deterministic least squares and stochastic least squares. The unbiasedness and optimality of the MLSs estimators are further verified. Then, based on the established MLSs algorithm, a new solution to simultaneous state and unknown input estimation (SUIE) problems is given. The proposed method is more concise and straightforward than the existing SUIE algorithms. The method provided in this article offers fresh insight into parameter/state estimation with unknown input.

期刊介绍： In the IEEE Transactions on Automatic Control, the IEEE Control Systems Society publishes high-quality papers on the theory, design, and applications of control engineering. Two types of contributions are regularly considered: 1) Papers: Presentation of significant research, development, or application of control concepts. 2) Technical Notes and Correspondence: Brief technical notes, comments on published areas or established control topics, corrections to papers and notes published in the Transactions. In addition, special papers (tutorials, surveys, and perspectives on the theory and applications of control systems topics) are solicited.
