Abstract:
In this paper, the experimental results obtained in the design and implementation of a self-tunning voltage controller for a micro energy system are analyzed. Two types of indirect adaptive self-tuning schemes are proposed. Both uses a recursive estimation scheme based on the well known Least Squares method. The difference between them is the controller formulation methodology: one uses the pole placement method and the other uses the generalized predictive control. Tests shows the comparison performance of the proposed adaptive controllers versus fixed digital controllers.
