Fuzzy Control Strategy Feasibility Analysis for ITER PF Powe

发布时间：2024-09-20 19:34

　　The International Thermonuclear Experimental Reactor(ITER)is one of the ultimate attractive solutions to sort the energy crisis by generating large amount of carbon-free energy.The Poloidal Field(PF)converter,as a significant part of the ITER device,plays essential role in the plasma shape and position control in vertical and horizontal direction.The AC/DC PF converter power supply is very complex,highly nonlinear and time varying in nature.Its physical model has a growing interest to realize the...
