Abstract

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 taking 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 was 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.

带惯性负载直流电机的离散时间建模与状态反馈控制

机电系统中的位置控制可以多次由直流（DC）电机执行。因此，文献中通过几种控制策略对这些设备的控制进行了研究。在这项工作中，提出了耦合负载直流电机的建模，包括获得主要系统参数的实验和动力学的离散化过程。离散化被考虑在内，以便允许控制器由计算机执行。根据所获得的模型，探索了状态反馈控制方法和观测器，为所考虑的直流电机创建了数字控制器。仿真和实验结果表明，该模型是有效的。此外，可以得出结论，所提出的控制策略在模拟和实验测试中都取得了适当的结果。
