The aim of the paper is to implement two degree of freedom digital fractional order proportional-integral-derivative (2-DOF FOPID) controller for speed control of DC series motor. Speed control is achieved by pulse width modulated control method through four quadrant chopper circuit. For realization of digital fractional order controller in integer order sense, pole-zero interlacing method is used. The controller parameters are tuned by using improved dynamic particle swarm optimization (IDPSO) technique. The effectiveness of proposed control scheme is simulated using FPGA (field programmable gate array)-in-loop wizard of MATLAB/Simulink. The performance comparison shows improvement with proposed controller as compared to integer counterpart.
