A New Approach to Design and Implementation of Multi-Layer Control in the IoT

In this research, the development of technical knowledge and the implementation of modern control strategies on the IoT platform has been investigated. In this regard, using multi-layer hierarchical control over the IoT platform enables the communication and transfer of information from lower layers to upper layers, and the ability to process data and provide of control solutions considering new conditions from upper layers to lower layers. One of the main applications of this approach is the control of high-inertia systems, by optimizing the local layer by the main layer. For this purpose, a two-layer controller has been considered, that controls the soil temperature and humidity time-delay systems in the bottom layer in the form of PID and IFTTT control, respectively. Meanwhile, the upper layer uses the obtained information and the differential evolution algorithm (DE) and ANFIS controller, adjust the PID controller coefficients applied to the subsystem and IFTTT workstations, respectively. This reduces the size and complexity of the hardware used in the lower layers and consequently reduces the costs involved. It allows the implementation of sophisticated controllers, especially on large-scale plants. On the other hand, it is also possible to control high-inertia systems. The simulation results and practical tests indicated that this control strategy was very effective in IoT platforms.
