Abstract: The paper presents a short survey of some topics related to speed control of electrical drives based on fuzzy PI controllers. In the beginning the conventional control systems of the main three motors mostly used in practice: DC motors, induction motors and permanent magnet synchronous motors are taken in discussion, emphasizing the way of their PI liner controller design. The paper presents how the fuzzy PI speed controllers may be developed for all three motors. A stability analysis of the fuzzy control of DC control system, based on circle criterion is presented. Modeling and simulation Simulink diagrams with transient characteristics for different functioning regimes are presented. A comparison of the quality criteria for fuzzy control systems and linear control systems is discussed. Some ways of implementation of the fuzzy speed controllers based on interpolation and neural networks is presented.
