Okvirno bo podan pristop modeliranja. Nato bo opisan problem vodenja, začenši z regulacijo toka in pozicije plazme do bolj zahtevne regulacije oblike preseka plazme. Predlagane rešitve segajo od preprostih PID regulatorjev do bolj zapletenih multivariabilnih regulatorjev. Predstavljen bo regulator, ki je izveden v največjem delujočem tokamaku JET (Joint European Torus, Culham, VB), imenovan "eXtreme Shape Controller", z dodatnim sistemom "Current Limit Avoidance", ki je bil izveden za reševanje problema zasičenja tokov v magnetnih navitjih.</span><span lang="EN-US" style="font-size: 11pt; font-family: Cambria, serif;" class=""><o:p class=""></o:p></span></p><p class="MsoNormal" style="margin: 0cm 0cm 12pt; font-size: 12pt; font-family: 'Times New Roman', serif; text-align: justify;">Predavanje bo v angleščini.<o:p class=""></o:p></p><p class="MsoNormal" style="margin: 0cm 0cm 12pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><b class=""><span style="font-family: Calibri, sans-serif; color: red;" class="">Lepo vabljeni!</span></b><o:p class=""></o:p></p><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><o:p class=""> </o:p></div><span style="font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><br clear="all" style="page-break-before: always;" class=""></span><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class="">We invite you to the 11th Institute colloquium in the academic year 2015/16.

Modelling issues will be briefly discussed, and then the control problem will be described, beginning with the control of current and position and progressing to the more challenging shape control. The solutions proposed vary from simple PIDs to more sophisticated MIMO controllers. Eventually, the controller implemented at JET, the eXtreme Shape Controller, will be presented, along with a system, called Current Limit Avoidance, which has been implemented to address the problem of current saturations.<o:p class=""></o:p></span></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class="">Cordially invited!</div></body></html>
