Hierarchical optimal control and stability of large-scale systems. (English) Zbl 0666.93002
There are three parts in this paper: (1) a state-regulating problem is solved for a very-large-scale system. The optimal-control laws are formulated with multiechelon-dynamical-hierarchical structure. A set of matrix equations which arises in formulating optimal-control laws is shown to be solvable in an alternative way; (2) the stability of such formulated multiechelon-hierarchical structure is analysed; (3) the number of levels of hierarchy needed in a multiechelon structure is calculated and also the order of the dynamic-state regulator required.
