Global formulations 330 $aClassical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations.Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases.Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchron 410 0$aISTE 606 $aElectric motors, Synchronous$xAutomatic control 615 0$aElectric motors, Synchronous$xAutomatic control. 676 $a621.46 701 $aLouis$b Jean-Paul$f1945-$0865189 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910138862203321 996 $aControl of non-conventional synchronous motors$91931103 997 $aUNINA
