Abstract:Hydroelectric plants are the main sources of energy in Brazil. For their correct functioning is essential to maintain the stability of the system; one way to ensure this is through the stability of the frequency, via the speed controller for such a task. Proportional-integral (PI) type controllers are used, in order to achieve desired performance and stability. To find suitable gains of the controller, multi-objective control techniques are applied, because their usefulness to represent the trade-off between c… Show more
