ABSTRACT

An experimental intelligent angular positioning fuzzy servomechanism excited by a nonlinear load based on a mechanical transient Pulse Width Modulation (PWM) is developed. This fuzzy positioning system is capable of reaching the angular position with high precision even when the response is affected by the application of different PWM nonlinear loads.

Keywords: Fuzzy servomechanism, nonlinear load, fuzzy rotating control.

 

RESUMEN

Se desarrolla un servomecanismo difuso de posicionamiento angular inteligente experimental perturbado por cargas no–lineales basadas en transitorios mecánicos generados mediante la modulación de ancho de pulso (PWM). El sistema de posicionamiento difuso desarrollado es capaz de alcanzar la posición angular con gran precisión aún cuando la respuesta es afectada por la aplicación de distintas cargas PWM no lineales.
