GRADIENT COORDINATION TECHNIQUE FOR CONTROLLING HIERARCHICAL AND NETWORK SYSTEMS
A. Ya. Fridman, O. V. Fridman · Systems Research Forum · 2010
We developed a gradient coordination technique for decentralized control in hierarchical and network systems. The technique is based on necessary and sufficient coordinability conditions that we proposed earlier for locally controlled hierarchies of dynamic systems. First, we describe a modeling shell suitable for monitoring and predicting behavior of network objects. Then we propose a gradient method to coordinate locally controlled hierarchies and networks. Efficiency of the technique is illustrated by mathematical modeling of a two-level control system for linear objects. The modeling has proved that usage of local control and coordination widens the stability range of the system for both external and structural disturbances as well as increases its speed by several times.
