Abstract :
This paper presents the fuzzy pre-compensated PI (FPPI) speed controller for permanent magnet brushless DC (PMBLDC) motor drive. Various aspects of DSP based implementation of PMBLDC motor drive system such as inverter, position and current sensing, reference current generation and PWM current control are discussed in detail. The fuzzy logic algorithm used in this work particularly suitable for digital control because of the simplified way of handling the rule base and considerable reduction of computation during defuzzification process. Transient performance of the drive system obtained using FPPI speed controller is compared with the conventional PI speed controller.
