Abstract: A control system connected to sensor and actuator via communication network plays pivotal role in a today's emerging world. The problem of obtaining a consensus in a group of networks connected agents is one of the major areas of research in the network control systems. In industry, a multi-motor system is very much in demand due to common load driven capacity, and cost saving. Coordinated speed plays vital role to control the in-flight movement of multi-rotor UAV/drones, producing hovering, tilting or other necessary flight control movements. Thus, this study uses a leaderless multi-agent consensus model to achieve coordinated control of network connected motor drives such that all the drives reach identical speed. Moreover, this study also incorporates event-based control, so that the continuous time controller update can be avoided, thus offering energy saving. To ensure stable system design, the Lyapunov stability criteria are used, while the obtained design is simulated in MATLAB. The simulated results endorse the design concept, such that the system attains a consensus on motor speed along with energy saving.
