Abstract: Present paper is analyzing the permanent magnet dc motor (PMDC) through state space variables so that command speed without consequence resulted from voltage and power and load fluctuations can be obtained. For this purpose, we should write equations of permanent magnetic motor and then by applying these equations and known methods of control, try for making desirable behavior of these motors, and by using MATLAB software in coding, analyzing real behavior of motor could be possible, and regarding to these results, planning for future of a system in front of short circuit and load fluctuation could be possible. We are trying to reduce dangers resulted from mistakes in experiments.
Keywords: Permanent magnetic motor, modern control, efficiency, permanent magnetic motors, control, permanent magnet motor, sensorless, torque fluctuation.
