    FPGA based DC motor speed and torque control
    (2019) Bouaou, Djameleddine; Souissi, Slimane; Bentarzi, Hamid
    This project describes a design and implementation of an FPGA based speed and torque control of a direct current motor. The speed and torque are controlled using the armature voltage variation technique. A dual H- bridge integrated circuit motor driver (L293D) is used to drive a separately excited DC motor. An Altera FPGA DE2 board is used to implement the digital controllers that regulate both the voltage and the armature current and hence the speed and torque. In general, the output speed of the DC motor is measured and compared with a reference. Thus, the armature voltage is continually adjusted to keep the measured speed as the reference while the load varies.
