The goal of this paper is to describe the different steps of the decentralized control design applied on a turboprop engine. An important part of the present approach is the interaction analysis, which leads to the choice of a decentralized strategy with a full compensator. After designing the control laws, the structured singular value approach has allowed to validate the robustness of these. Control laws have finally been interpolated before implementation on the non-linear simulation model of turboprop engine.
