According the importance of controlling the max¬i¬m¬¬um speed and overshoot in electric motors, and also according to the fact that at the start of a two-mass system with a resonance ratio controller, we will see severe fluctuations in the speed. The control the motor maximum speed in speed desired value is aim in this paper. To take action to achieve this goal, we will use the design incorporating a self-organizing fuzzy control system with a coefficient of resonant two-mass system. Self-organizing fuzzy controller is a combination of fuzzy control and adaptive, which along with the combination of self-organizing fuzzy control meth¬o¬ds, can created instructional with the ability to modify the rules in the knowledge base and incorporated into it, twomass system with a resonance ratio control system, the maximum eng¬ine speed can be adjusted to any desired value.
