A comparison of fault-tolerant control strategies for a PMSG-based marine current turbine system under generator side converter faulty conditions. This  paper  describes  fault-tolerant  control  strategies  for  a  Permanent  Magnet  Synchronous  Generator  (PMSG)-based  Marine  Current  Turbine  (MCT)  dealing  with  the  generator-side  converter under faulty conditions. MCT system mainly used PI controllers. However, this type of  controllers  is  very  sensitive  to  faulty  conditions  such  as  an  open  circuit  faults  in  the  generator-side  converter.  As  consequence,  the  MCT  system  represents  a  high  decrease  in  its  power  generation  and  dynamic  performances.  In  this  faulty  context,  firstly,  a  fault  tolerant  structure  consists  in  requiring  only  minimum  hardware  modifications  to  the  converter  is  proposed. In the second part, a backstepping and a second-order sliding mode nonlinear control are  therefore  investigated  for  fault-tolerant  control  purposes.  A  comparison  between  the different control strategies is proposed to prove the most robust one. | Toumi, Sana
