  • fragmentation based distributed control system for software defined wireless sensor networks
    IEEE Transactions on Industrial Informatics, 2019
    Co-Authors: Hlabishi Isaac Kobo, Adnan M Abumahfouz, Gerhard P Hancke
    Abstract:

    Software-defined wireless sensor networks (WSNs) are a new and emerging network paradigm that seeks to address the impending issues in WSNs. It is formed by applying software-defined networking to WSNs whose basic tenet is the centralization of control intelligence of the network. The centralization of the Controller rouses many challenges such as security, reliability, scalability, and performance. A distributed control system is proposed in this paper to address issues arising from and pertaining to the Centralized Controller. Fragmentation is proposed as a method of distribution, which entails a two-level control structure consisting of local Controllers closer to the infrastructure elements and a global Controller, which has a global view of the entire network. A distributed Controller system brings several advantages and the experiments carried out show that it performs better than a central Controller. Furthermore, the results also show that fragmentation improves the performance and thus have a potential to have major impact in the Internet of things.

  • multi agent based distributed control architecture for microgrid energy management and optimization
    Energy Conversion and Management, 2016
    Co-Authors: Reyasudin Basir M Khan, Razali Jidin, Jagadeesh Pasupuleti
    Abstract:

    Abstract Most energy management systems are based on a Centralized Controller that is difficult to satisfy criteria such as fault tolerance and adaptability. Therefore, a new multi-agent based distributed energy management system architecture is proposed in this paper. The distributed generation system is composed of several distributed energy resources and a group of loads. A multi-agent system based deCentralized control architecture was developed in order to provide control for the complex energy management of the distributed generation system. Then, non-cooperative game theory was used for the multi-agent coordination in the system. The distributed generation system was assessed by simulation under renewable resource fluctuations, seasonal load demand and grid disturbances. The simulation results show that the implementation of the new energy management system proved to provide more robust and high performance controls than conventional Centralized energy management systems.

  • Wireless Event-Triggered Control for Water Irrigation Systems
    2020
    Co-Authors: Lont J.j.
    Abstract:

    The application of optimal control structures for water irrigation systems (WISs) can be enabled by applying wireless event-triggered control (ETC). The term WIS, is used to describe open-water channels, that are mainly used to supply water to farmers all around the world. The water levels in these channels need to be controlled, but because of the large scale of WISs, it is very expensive to create Centralized control structures when using wired connections between individual sensors, actuators and a Centralized Controller. Previously, WISs were typically controlled using individual deCentralized (non-communicating) Controllers. Applying wireless technologies enables communication between (smart) sensors, actuators and a Centralized Controller without the expense of installing and maintaining cables over lengths of kilometers. To create such a wireless infrastructure, a network needs to be designed, consisting of multiple nodes that are able to communicate with each other over wireless. Each sensor and actuator will be connected to (or integrated in) a node, just like the Centralized Controller needs to be connected to a node. To minimize the costs related to creating such an infrastructure, the nodes should have their own power source in order to prevent that a maintenance worker has to change the batteries of the nodes periodically. The nodes could be powered using a solar panel, or by using energy harvesting, which could be done by using a turbine to extract energy from the flow in a water channel. When using such energy sources, it is important to minimize the power consumption of the nodes. Most of the consumed power is used in communication when transmitting information. By applying ETC, the amount of communication between the individual parts of the control system is minimized, while still retaining good closed-loop system control using a Centralized Controller. In this research, techniques on wireless control, ETC and WIS control are combined and the application of an event-triggered Centralized Controller is presented using simulations, as well as the achievable reduction in communication compared to regular periodic control. Furthermore, a cyber-physical lab setup is designed and built which makes it possible to test these techniques in the Delft Center for Systems and Control (DCSC) lab.Systems and Contro
