In recent years, microgrids have surfaced as a distributed and embedded energy production alternative. This literature review analyses agent-based model systems with distinct approaches that model, control, and supervise microgrids, establishing a viewpoint for the transition to renewable energy, which engulfs energy security, and technology adoption. Procurement of microgrids utilizing energy transactions between end-users and implementing agent-based models has derived a better understanding of local and micro-energy markets. This literature review explores community microgrids deployment's social dynamics and technical performance from a micro point of view. Finally, we present a roadmap for long and short-term use of agent-based models to access energy security via local energy markets, energy storage systems and community-based microgrids in rural areas. The results of this comprehensive review give way to further research questions on the use of agent-based models to improve the adoption of energy storage systems, the use of technologies to accelerate the creation of local energy markets, and the successful deployment of community-based microgrids.

Automated Manufacturing System. The plant model is obtained from the process definition and material-handling tasks, according to the ISA-88 and ISA-95 standards, including the communication of different local controllers. Then, a hierarchical-decentralized supervisory control scheme is implemented where the low-level is composed of a decentralized supervision of the task precedences and storage limitations restrictions. The high-level supervisor deals only with the product recipes using the subset of events related to the process tasks only. Therefore, the scheme
provides a clear separation between the equipment operations and the product manufacturing actions. The supervisory control is implemented on a PC communicated through a network of PLC’s and local controllers with industrial robots.

T... more This paper presents a two-level control strategy for the trajectory tracking of the quadcopter. The external loop is designed to move the translational dynamics of the robot to follow smooth parametric functions using an appropriate variables substitution. The outer loop generates the desired trajectories of the orientation angles, which are controlled in the inner loop. The parameter gains are calculated using linear optimal control in order to minimize the energy consumption of the rotors. The control architecture is designed to be compatible with standard electronic platforms of commercial quadcopters and incorporates the purpose of maximizing flight time, an important requirement in real applications of multi-rotor aerial vehicles. Some numerical simulations show the performance of the control approach.
