Resumen

Introducción: La aeroponía permite la posibilidad de cultivar plantas, en lugares donde la agricultura convencional de campo abierto es difícil. El uso de la tecnología permite mejorar la eficiencia de los procesos, aunque se requiere incorporar algunas mejoras y soluciones en los sistemas de suministro energético y control del riego.

Objetivo: Implementar una fuente autónoma de suministro energético y un sistema de control del riego para la producción de alimentos libres de pesticidas.

Metodología: El sistema autónomo se diseñó utilizando la herramienta Matlab-Simulink-MPLAB, para desarrollar el modelo de control y aplicarlo al cultivo. Además, se programó un dsPIC para los algoritmos de control del ciclo de riego utilizando bloques Matlab-Simulink.

Resultados: Los resultados muestran que el ciclo de riego y el suministro de energía, ayudan a mantener plantas uniformes en el cultivo durante el periodo de las pruebas, lo que permite a su vez incorporar mejoras en el desarrollo de los cultivos aeropónicos.

Conclusiones: Cultivar de manera aeropónica reduce el uso de pesticidas, espacio, agua y nutrientes. La automatización en los sistemas de irrigación y de suministro de potencia, permite lograr un buen crecimiento en el cilantro, lo cual se puede evidenciar mediante el incremento en los niveles de peso y volumen, registrados en las mediciones de las plantas de prueba.

Palabras clave: Alimentos libres de pesticidas, aeroponía, sistemas de irrigación autónoma, producción limpia, fuente de potencia eléctrica autónoma
