Compared to classical wired controlled systems, NCSs possess many advantages. In this paper, we propose the modeling and networked control of two-rigid link robot arm. To deal with the time delays that may occur during communication between the components of the system through the network, a model of the system was first determined, and second, PID controllers were designed based on the obtained model and using the stability region boundary locus technique. To demonstrate the validity of the proposed approach, numerical simulations were conducted using TrueTime, Simscape, SimMechanics, and Simulink with the MATLAB environment91520209152020375382https://www.wseas.org/multimedia/journals/control/2020/a785103-1015.pdf10.37394/23203.2020.15.39https://www.wseas.org/multimedia/journals/control/2020/a785103-1015.pdf10.1016/j.mechatronics.2020.102348Jiang, Y., Yang, C., Wang, Y, Ju, Z.,Li, Y.,& Su, C.-Y.
