A New Systems Year

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

A New Method for Time-Delay Compensation in Control Systems

In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...

A New Year, A New Beginning

The Day of Epiphany is one of the seven principal celebrations of the church year, right up there with Christmas, Easter, Pentecost and All Saints’ Day, but because it rarely falls on a Sunday, it doesn’t get the same attention as those other holidays. The word “epiphany” means “to manifest” or "make known," and during this Epiphany season, all of our readings will, in some way, reveal the true...

A New Year

Iwish you all a happy and prosperous New Year, and I look forward to continuing to bring CG&A to all of you. I’m writing this message in November 2011, with fresh memories of activities I took part in at VisWeek 2011. This year, VisWeek had more than 1,000 attendees—an all-time record. Congratulations to the organizers! At VisWeek, I participated in the well-attended Meet the Editors panel, alo...
