Optimal Control Algorithms for WNCS Implemented with IoT Tools

Abstract:

In this work, the implementation, simulation and analysis of LQG and PID algorithms have been carried out; applied in a DC motor with brushes by means of a control system in a WNCS wireless network, where the network is part of the closed control loop, using the protocol MQTT for communication between the broker and the plant. The performance of each of the control algorithms was evaluated through simulations in the network, which allowed determining the dynamic response parameters of the system. With the data obtained, the algorithms were implemented using a development tool based on the flow for visual programming, with the purpose of controlling and monitoring wirelessly or even through a mobile device remotely in real time, thus becoming an IoT application. Optimum performance is corroborated through communication and control tests when the plant is subjected to disturbances.
