Control loop for finding initial translator position of linear synchronous motor

This article presents a simple and reliable method for controlling the relative orientation between the two magnetic fields of a permanent magnet synchronous motor. Finding the initial (at motor powering- up time) value of this relative location is essential for the proper operation of the motor. After showing the system controllability, the utilized feedback control loop finds this initial relative orientation quickly and accurately. Further, using the proposed method allows considerable cost saving, as a transducer that is usually used for this purpose can be eliminated. The cost saving is most obvious in the case of linear motors and angle motors with large diameters. The way the problem is posed is an essential part of this work, and it is the reason behind the apparent simplicity of the solution. The method proposed relies on a single sensor, and it was tested when a relative encoder was used.

From the 'mad' poet to the 'embodied' poet: reconceptualising creativity through cognitive science paradigms

 Written by the author of three collections of poetry, this paper contests the enduring stereotype of the ‘mad’ poet, present in Romantic, psychoanalytic and psychological theories of creativity. Mobilising theories of embodied cognition, it offers a demystified and de-pathologised vision of poiesis and poetry. The paper focuses on three traits typically associated with the ‘mad’ poet in popular representations and theoretical understandings of that figure: extreme emotionality; divergent thinking; and a tortured unconscious. Using findings in the cognitive sciences, the essay demonstrates how emotional experience, divergent thinking, and the unconscious are integral parts of brain functioning, rather than traits exclusive to psychopathology. Poiesis is not informed, in any essential way, by madness but rather by the normal conditions of embodied cognition.
