Combinig the strategies of costate prediction approach by Hassan and Singh and the time-delay coordination algorithm by Tamura, the variable prediction-time decomposition technique is put forward. Using the technique, the nonlinear three-level hierarchical optimization structure is formulated. 文中将Hassan共态预测法和Tamura时延算法的主要思想相结合,提出和使用了预测变量一时间分解方法,导出了非线性三级递阶优化结构。
