Abstract
This paper proposes a straightforward and systematic way of designing a decentralized control. The main setup steps are the interaction analysis, the decoupling of the interactions, and the design of the controllers. The proposed procedure is applied on identified models of a turboprop engine. The interaction analysis leads to the choice of a decentralized strategy with a full compensator. On each operating point, an inverted decoupler is selected in order to reduce interactions, and PI controllers are designed using an analytical method. The control laws robustness is then ensured using the structured singular value approach. Finally, control laws performances are validated using the non-linear simulation model of turboprop engine.
