Overview of models and control methods for step motors and permanent magnet motors

This overview is devoted to the description of step motor models and permanent magnet motor models that can be used to design the control law for these devices. These motors are widely used in various practical applications and scientific equipments due to its high accuracy. A number of works on the design of various control laws for these electrical machines are described. The features of each model and the features of obtained considered control laws are given from the point of view of achieving certain physical properties in the obtained closed-loop systems.
