Annotation: A permanent magnet synchronous motor electromagnetic torque control algorithms providing high dynamic performances based on the nonlinear automatic control theory were developed and studied. The new nonlinear control algorithm, called «differential control», that provides accurate torque control with a quick response, was developed. This algorithm is based on equality of controlled variable derivative sign and its error sign.
