Abstract :This paper deals with the speed control of a permanent-magnet brushless direct current insert ignore into journalissuearticles values(PMBLDC); motor. A fractional order PID insert ignore into journalissuearticles values(FOPID); controller is used in place of the conventional PID controller. The FOPID controller is a generalized form of the PID controller in which the order of integration and differentiation is any real number. It is shown that the proposed controller provides a powerful framework to control the PMBLDC motor. Parameters of the controller are found by using a novel dynamic particle swarm optimization insert ignore into journalissuearticles values(dPSO); method. The frequency domain pole-zero insert ignore into journalissuearticles values(p-z); interlacing method is used to approximate the fractional order operator. A three-phase inverter with four switches is used in place of the conventional six-switches inverter to suggest a cost-effective control scheme. The digital controller has been implemented using a field programmable gate array insert ignore into journalissuearticles values(FPGA);. The control scheme is verified using the FPGA-in-the-loop insert ignore into journalissuearticles values(FIL); wizard of MATLAB/Simulink. Improvement in the overall performance of the system is observed using the proposed FOPID controller. The energy efficient nature of the FOPID controller is also demonstrated.
