RESUMO

Despite being used in the industry for more than 20 years, Model Predictive Control (MPC) has not found many applications in the field of rotating machinery controI. The majority of the applications today are chemical and petrochemical processes. However, some results obtained by other authors for the control of gas and steam turbines, suggest that its use can be interesting for the control of this type of machine, and in particular, for the control of hydraulic turbine generators. The objective of this work is to explore the possibility and to discuss the advantages and disadvantages of the application of this method on the control of a Francis hydro turbine generator. We start the discussion presenting a description of the MPC and detailing the algorithm used by the controller. After that, a state space model of the system to be controlled is developed. Finally the method is applied for the control of the hydro turbine and the results obtained trough simulation are discussed
