Parametric Identification to an Electronic Ballast System - Hid-Mh Lamp Based in Subspaces Methods

The following work propose a parametric identification to an electronic ballast prototype -- 250 watts HID-MH lamp, using an non recursive process as identification methods based in subspaces. The lack of a mathematical model that describes the behavior of the electronic ballast´s non controlled output voltage, impede design a controller for this output variable. For these reason is imperative to find a mathematical representation that describes the real behavior of the system.
