DC Motor Speed Control via Fractional-Order PID Controllers

This work proposes several designs for controlling the DC motor speed of a car. Such a motor is broadly used in numerous applications like blowers, lathe machines, cranes, elevators, milling machines, fans, drilling rigs, etc. to achieving our aim, two optimization algorithms, particle swarm optimization and bacterial foraging optimization, will be executed to adjust the proposed controllers’ parameters. Accordingly, four Fractional-order PID controllers (FoPID-controllers) will be formed in agreement with two types of schemes (Outstaloup’s and continued fraction expansion (CFE) schemes), which will be used to approximate the yielded Laplacian operators s ^±α, where 0 < α < 1.
