This article describes an encounter between servomechanism innovator, digital computing pioneer and creator of system dynamics, Jay Forrester, Isaac Asimov, renowned author science fiction (including “The Foundation Trilogy” its fictional discipline psychohistory) works popular science. Their lengthy exchange took place at a workshop in 1975 four descriptions it are extant. What emerges passing...

In numerous applications across all science and engineering areas, there are optimization problems where both the objective function constraints have no closed-form expression or too complex to be managed analytically, so that they can only evaluated through experiments. To address such issues, we design a global technique for with black-box constraints. Assuming Lipschitz continuity of cost co...

In this paper, an state-space approach to deadbeat servomechanism design is proposed using multirate input control. This paper focuses advantage of multirate control over conventional single-rate control. To achieve settling time specified, multirate controllers require less frequent sampling of measurement than single-rate ones. Multirate input mechanism can yield shorter settling time than si...
