PERFORMANCE INVESTIGATION OF FUZZY LOGIC CONTROL OF PHASE CONTROLLED CONVERTER FED DC MOTOR DRIVE

Abstract

Fuzzy logic is given grater emphasis in industrial control applications. This scheme proposed "performance investigation of fuzzy logic control of phase controlled converter fed DC motor" it is PC based with C programming and the designed controller has two loops with inner current control loop and outer speed control with fuzzy compensation used to linearize the converter transfer characteristics in discontinuous mode. The fuzzy controller designed and evaluated by MATLAB simulation. The fuzzy controller used to generate the change in control voltage for thyristor converter .which in turn changes the armature voltage of converter the simulated results are compared with experimental results.
