Global formulationsClassical 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 synchronISTEElectric motors, SynchronousAutomatic controlElectric motors, SynchronousAutomatic control.621.46Louis Jean-Paul1945-865189MiAaPQMiAaPQMiAaPQBOOK9910138862203321Control of non-conventional synchronous motors1931103UNINA
