Abstract

The paper presents the theory of control systems for electrical drives based on fuzzy logic, from the author's point of view. The paper offers practical answers at questions related to the design of speed control systems based on fuzzy PI speed controller: what is the adequate structure of fuzzy controller, the number of rules fuzzy values, how to assure stability, implementation, control system quality criteria. The conventional design method for the linear speed control systems is presented as a comparison base. An example of fuzzy control systems for d.c. drives is given, with its modelling, simulation, design, transient characteristics and quality criteria.
