Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Application of genetic algorithm in parametric optimization of the circuit-systems with pulse-width modulation N.N. KUCYI, N.D. LUKYANOV In this paper we consider the problem of parametric optimization of pulsed systems with PWM elements. We developed an approach to solving the problem of parametric optimization based on genetic algorithm. Showing the highlights of roulette selection scheme parents, as well as its formalization for program implementation. Presents a methodology the proof of performance of the algorithm, based on the introduction of conditions limiting the initial values of adjustable parameters. As example we consider the optimization of performing modulation of both the first and second kind. The modulation characteristic of shows plots in the primary and optimal conditions and related graphics transients. Keywords: genetic algorithm, the roulette scheme, parametric optimization, the PWM unit. Contacts: E-mail: Kucyinn@mail.ru Pp. 37-42.
