Abstract
Description
Los autómatas programables (PLC's), los módulos de adquisición de datos (feldpoint) y los microcontroladores, son algunos de los dispositivos usados actualmente como plataforma para los sistemas de control, dichos sistemas permiten realizar tareas repetitivas con precisión y seguridad, buscando garantizar la calidad de los productos en el proceso de producción. Algunas de las características fundamentales de los dispositivos de control son: velocidad de respuesta, tiempo de muestreo, precisión y estabilidad en los procesos industriales, estos datos no siempre son ofrecidos por los fabricantes, dificultando así la selección adecuada del sistema de control a implementar. En el presente artículo producto de un trabajo de Investigación se comparan las funcionalidades de 3 dispositivos de control, implementados en un péndulo invertido que es accionado mediante un sistema electrohidráulico y un sistema electrónico de potencia, este mecanismo es diseñado y construido para servir como punto de comparación entre los diferentes dispositivos de control, ya que dependiendo del diseño del péndulo y de las características del mismo, es posible evaluar tanto la resolución como el tiempo de respuesta de dispositivos lógicos programables, estos parámetros de precisión, son vitales para la correcta selección de los sistemas de control implementados en la industria.

Some of the principal features of control devices are: response speed, sampling time, precision and stability in industrial processes, these data are not always offered by manufacturers, thus hindering the appropriate control system selection to implement. This research work compares features of three device control, implemented in a pendulum drive by a electrohydraulic and electronic system, this mechanism is designed and built to serve as a point of comparison between different control devices, since depending on the design of the pendulum and its characteristics, is possible to evaluate the resolution and response time of these devices, these precision parameters are vital for the correct selection of control systems deployed in the industry.
