In classical control of brushless dc motors, flux distribution is assumed trapezoidal and fed current is controlled rectangular to obtain a desired constant torque. However, in reality this assumption may not be correct due to nonuniformity of magnetic materials and design trade-offs. These factors together with current controller limitation, can lead to an undesirable torqueripple. Hence torqu...
