Cloak of Law on Stature of Morality: a critical view on Patrick Devlin's attitude toward legal enforcement of conventional morality

The relationship between morality and law is one of the issues that has provoked considerable controversies. Among others, an important discussion is whether obeying “conventional morality” in public and/or private spheres should be legally enforced by legislators. In this paper, we will look at the controversies over the issue of the “legal enforcement of morality” in the well-known debate between Herbert Hart and Patrick Devlin. In light of Richard Hare's moral philosophy, we will begin by distinguishing three realms of morality. We will then clarify Deviln's view on “conventional morality”, employing the terminology derived from Hare's moral philosophy. After elaborating the implications, consequences, and roots of “conventional morality” in Devlin's view, we will turn to the relation between law and “conventional morality”. Finally, we will criticize Devlin's approach and highlight our objections to his account. By showing the flaws of Devlin's conception of “conventional morality,” we will challenge her legal view of morals

Evolutionary Algorithms for PID controller tuning: Current Trends and Perspectives

[ES] Los controladores PID continúan siendo una solución fiable, robusta, práctica y sencilla para el control de procesos. Actualmente constituyen la primera capa de control de la gran mayoría de las aplicaciones industriales. De ahí que un número importante de trabajos de investigación se han orientado a mejorar su rendimiento y prestaciones. Las líneas de investigación en este campo van desde nuevos métodos de ajuste, pasando por nuevos tipos de estructura hasta metodologías de diseño integrales. Particularizando en el ajuste de parámetros, una de las formas de obtener una solución novedosa consiste en plantear un problema de optimización, el cual puede llegar a ser no-lineal, no-convexo y con restricciones. Dado que los algoritmos evolutivos han mostrado un buen desempeño para solucionar problemas complejos de optimización, han sido utilizados en diversas propuestas relacionadas con el ajuste de controladores PID. Este trabajo muestra un revisión de estas propuestas y las prestaciones obtenidas en cada caso. Así mismo, se identifican algunas tendencias y posibles líneas de trabajo futuras.[EN] PID controllers are a reliable, robust, practical and easy to implement control solution for industrial processes. They provide the first control layer for a vast majority of industrial applications. Owing to this, several researches invest time and resources to improve their performance. The research lines in this field scope with new tuning methods, new types of structures and integral design methods. For tuning methods, improvements could be fulfilled stating an optimization problem, which could be non-linear, non-convex and highly constrained. In such instances, evolutionary algorithms have shown a good performance and have been used in various proposals related with PID controllers tuning. This work shows a review of these proposals and the benefits obtained in each case. Some trends and possible future research lines are also identified.Este trabajo ha sido realizado parcialmente gracias al apoyo del Ministerio de Economía y Competitividad (Gobierno de España) mediante los proyectos TIN2011 - 28082, ENE2011- 25900; la Generalitat Valenciana mediante la iniciativa GV/2012/ 073 y la Universitat Politècnica de València a travès de la beca FPI-2010/19 y la iniciativa de investigacion PAID-06-11.Reynoso Meza, G.; Sanchís Saez, J.; Blasco Ferragud, FX.; Martínez Iranzo, MA.
