Resumen

El objetivo general de esta línea de investigación es lograr un control preciso de fase y amplitud en magnetrones para su aplicación en aceleradores de partículas. Como primer paso fundamental, este trabajo presenta el modelado y la simulación eficiente de magnetrones sincronizados por inyección. El principal desafío radica en que el modelo de circuito equivalente es un sistema oscilatorio "stiff", lo que provoca que los métodos estándar requieran tolerancias extremadamente bajas y largos tiempos de computación. Este artículo evalúa y compara diversos métodos numéricos en Keysight ADS, MATLAB/Simulink y Julia, utilizando Dynamic Time Warping para cuantificar el error sin penalizar derivas puramente temporales. Tras identificar los algoritmos óptimos para una simulación rápida y precisa, se demuestra que este modelo es apto para el diseño de estrategias de control. Como prueba de concepto, se implementa un lazo de control Proporcional-Integral sintonizado mediante SIMC, evidenciando la viabilidad de controlar las dinámicas lentas de fase y amplitud sobre el modelo oscilatorio no lineal.
