Novel Robust Control of Hydrogenerator: the synergetic approach

Usage of renewable energy and necessity to consider disturbances require application of fundamentally new modern control theory to a hydrogenerator nonlinear robust control. This paper presents a synergetic design technique of nonlinear robust control laws for hydrogenerator in accordance with integral adaptation principle of synergetic control theory. The obtained control laws provide implementation of desired technological invariants (control targets), i.e. stabilization of terminal voltage and ensure synchronous operation with the power supply network as well as suppression of external and parametric disturbances (so-called parametric robustness). This suppression is carried out without the construction of observers and it doesn't require operational identification of disturbances.
