    Model Based PI Controller Design and Test of a DC Motor Using Root Locus
    (2019) Beldek, Ulaş; Mahmood, Ahmed Imad; 59950
    :In this paper the mathematical model of an experimental DC motor control system is constructed in a simulative environment for speed (angular velocity) control process and a PI controller is designed using root locus technique. The designed controller is then tested in different scenarios with varying reference signalsand changing disturbance load conditions. The designed controller demonstrated satisfactory results in simulations.

    Simulative and real time DC motor speed control
    (2016) Mahmood, Ahmed Imad
    DC motor velocity control is one of the most commonly encountered control applications in literature as DC machines are exclusively used in industrial applications. The DC motors are assumed to have linear and stable characteristics, and for this reason they are supposed to be controlled easily. However that is not the case in real time applications. This thesis provides a real time controller design approach in cooperation with system identification. Primarily the linear mathematical model of an experimental DC motor speed control system set-up is constructed in simulation and this model is used to obtain a controllerfor the speed control mission yet the controller obtained in the simulation turn out to be unsuccessful in the real time application. Hence, a real time system identification step is executed to attain an approximate system linear model and it is observed that identified system structure varied from the mathematical model significantly. Finally, A new controller is designed for the identified system and it verified by different tests that this controller operates comparably well in real time applications.
