| 中文摘要 |
| 为克服线性大系统参数估计问题的维数灾难，本文提出一种目标补偿协调算法。它的主要特点是不用Lagrange乘子作协调变量，而通过对子问题的目标引入补偿项来协调它们，从而简化了协调结构。理论分析和实例计算表明，它的收敛性较好，适宜在多处理机系统上实现，由于整体算法和文献[1]的平行分解算法。 |
| 英文摘要 |
| In order to overcome the so called “dimensional disasters” caused by the parameter estimation problem of a large-scale linear system, an objective compensated coordination approach is proposed in the paper. Its main feature is that the coordination is realised by introducing compensation terms into the subproblems instead of using Lagrangian multiplier as the coordination variable, so the coordination structure is simplified. Theoretical analysis and applied calculation show that its convergence character and calculating time are better and less than those of the parallel decomposition approach proposed in [1] and the whole one. |
