We introduce the Synergetic approach, which brings great improvements in computer modeling and simulation of power electronic systems. Essentially. the process involves synthesis of control laws that result in collapse of (at least two) initially high-dimension models into a single model of lower-dimension. The technique requires creation of state space attractors, artificial manifolds. that reflect the desirable operating regimes of the dynamic system We explain the process and give example results.
Power systems are nonlinear multidimensional and multichannel complex objects. There are some structure and parameter uncertainties in power systems. For uncertainties compensation are used robust and adaptive control methods. The sliding mode control theory is one type of the robust control theories, which can obtain low sensitivity to object parameters changes. Therefore, new approach of nonlinear sliding mode control theory is shown in this paper. It's called synergetic sliding mode control. Here is described the procedure of synergetic sliding mode control for nonlinearly controlled objects. Proposed procedure is based on aggregated regulators analytical design (ARAD) method -the basic method of synergetic control theory. Application of this theory has been reviewed for synthesis of synchronous generator (SC) excitation nonlinear robust control law. Robustness and control performance of the proposed method are examined by numerical simulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
