Inverter for microturbines based on multiobjective genetic algorithm

Abstract:

In this paper, authors present a new design method for Pulse Width Modulation inverters in microturbines by using a multiobjective genetic algorithm. The design problem is converted to an equivalent optimization problem, and then a multiobjective genetic algorithm is adopted to find a solution. The genetic algorithm is proposed to design a fuzzy controller. In this GA approach, an individual is constructed to represent the fuzzy controller. Multiobjective genetic algorithm confers a number of advantages over conventional multiobjective optimization methods by evolving a family of Pareto-optimal solutions rather than a single solution estimate. This optimal fuzzy controller is suitable for the Specific Harmonic Elimination PWM technology, as demonstrated by the examples given in this paper. © 2005 IEEE.
