摘要

给出了方程误差与输出误差自适应算法之间的关系。它导致了对输出误差偏差和稳定性的明确看法。结果表明，通过控制自适应增益，可以在输出误差中实现理想的稳定性和偏置特性之间的权衡。复合回归算法(CRA)被引入作为影响这种权衡的一种手段，独立于增益。输出误差显示在CRA的一个特殊情况下。用一个定理给出了CRA的稳定性约束，并讨论了该算法的偏置性质。

The composite regressor algorithm

A relation between equation error and output-error adaptive algorithms is presented. It leads to a clarified view of output-error bias and stability. It is shown that a tradeoff between desirable stability and bias characteristics can be achieved in output error by manipulation of the adaptive gain. The composite regressor algorithm (CRA) is introduced as a means of affecting this tradeoff, independent of the gain. Output error is shown to a special case of CRA. A stability constraint for CRA is developed in a theorem, and the bias properties of this algorithm are discussed.<>
