ALVES, Uiliam Nelson L. T. et al. Discrete-time modeling and state feedback control of a DC motor with inertial load. J. appl. res. technol [online]. 2022, vol.20, n.6, pp.718-728.  Epub 08-Mayo-2023. ISSN 2448-6736.  https://doi.org/10.22201/icat.24486736e.2022.20.6.1304.

The position control in electromechanical systems can many times be performed by direct current (DC) motors. Due to this, the control of these devices is studied via several control strategies in the literature. In this work, the modeling of a direct current motor with coupled load is presented, including the experiments performed to obtain the main system’s parameters and the dynamic’s discretization process. The discretization is taken into account in order to allow the controller to be performed by a computer. From the obtained model, the state feedback control approach along with an observer were explored to create a digital controller for the considered DC motor. The obtained results, both from the simulation and the experimental setup, show that the obtained model is valid. Moreover, it is possible to conclude that the proposed control strategy conducts to appropriate results both in simulations and in experimental tests since the closed-loop system matches the performance requirements within the limitations of the considered prototype.
