Design of Digital Controllers for Permanent Magnet Torque Motors

The design of control system can be divided into two steps. The plant has to be converted into mathematical model form, so that its behavior can be analyzed. Then an appropriate controller has to be designed in order to get the desired response of the controlled system. In this paper, the linear model of a Permanent magnet torque motor (PMTM) is considered and three controllers, digital PID controller with two forms of positional and velocity, a deadbeat controller and pole placement controller method are designed and due to a comparison between them, the best controller for this kind of plants will be chosen.
