Fuzzy Logic Controller Based Four Phase Switched Reluctance Motor

Abstract

The switched reluctance motor drives has evolved as an alternative to conventional motors in variable speed drives because of advantages like simple and rugged structure, absence of rotor winding, adaptability to harsh environments like coal mining, high speed operation etc. Because of nonlinearity, torque ripple is high in the motor. Switched reluctance motors (SRM) have many advantageous characteristics comparing to those of the conventional AC and DC machines. The mechanical simplicity in construction of the SRM can be seen through their purely laminated-steel structure without permanent magnets, rotor windings and squirrel-cage bars. Thus, SR machines offer high reliability and robustness in operation. The Switched Reluctance Motor (SRM) has highly gains interested in many industrial applications. On the other hand the SRM also have the disadvantage points such as high torque ripple and nonlinearity characteristic. This paper presents the development of the drive system for a four-phase 8/6 switched reluctance motor with fuzzy logic controller for testing and obtaining characteristics of the SRM. By using MATLAB/SIMULINK software.
