Abstract: Production systems are using mechanical machines with motion control systems based on electrical motors. Assurance of good empirical control quality criteria is the main condition in electrical drives. The control of electrical drives provides strong incentives to control engineering in general, leading to the development of new control structures and their introduction to the other area of control. The paper presents a short survey of control quality criteria defined on speed and load torque disturbance responses and their importance in production quality. New control methods as fuzzy logic and interpolation between rules assure better values for main quality criteria and robustness at errors at parameter identification and load torque disturbance influence.
