Abstract

A nonlinear feedback control design methodology for a permanent magnet brushless DC motor is presented. A nonlinear state variable model for the motor is obtained and is subsequently transformed into a linear model by use of a diffeomorphism. Standard linear state space feedback control theory is applied in the new coordinate system and the resulting control law is then related back to the original coordinates. Computer simulations of the resulting closed-loop system are described
