Robust multimodel control applied on hydraulic turbine model

The paper deals with the departition of nonlinear system into several linear models and application of multimodel control, robust control and their combination on hydraulic turbine model. Controller design will be done in the frequency domain using the Edge Theorem and the Neymark D-partition method using the affine model. The proposed method guarantees stability and performance in form of the required degree of stability. Hydraulic turbine model is analyzed as system with unstructured uncertainty and robust stability condition is included in controller design. Multimodel and robust control approaches are presented in details, compared and used for derivation new approaches based on Edge Theorem combining advantages of both ones.
