Structural selection for decentralised control schemes

This paper considers a structural approach for selection of the control structure aiming at facilitating the design of decentralised control schemes. This requires the selection of inputs, outputs, as well as their coupling (selection of decentralisation structure) that will allow the solvability of a variety of decentralised control problems, such as pole assignment by decentralised output feedback, decentralised dynamic controllers etc. The overall approach is based on the use of necessary and sufficient conditions for generic and exact solvability of decentralised control problems, which are expressed in terms of properties of Plücker invariants and Markov type matrices. The approach is based on generic classification of desirable input and output partitions and parametric design of invariants.
