Abstract :
A nonlinear observer for the permanent magnet (PM) stepper motor is considered. Specifically, the method of A.J. Krener and W. Respondek (1985) is used to construct a nontrivial full-order speed observer that has linear error dynamics. The procedure is validated by experimental results. Reduced-order observers are constructed by inspection
