Special Issue Information

Dear Colleagues,

In the rapidly advancing landscape of science and technology, the escalating complexity of dynamic systems poses daily challenges, compelling the scientific community to unite in a concerted effort to enhance our understanding. This imperative collaboration gives rise to innovative approaches grounded in mathematical foundations that are aimed at surmounting the intricate hurdles inherent in the quest to refine essential products and services. Addressing real-world phenomena requires continuous development of mathematical approximations for dynamical systems, introducing additional complexities in their practical application.

In response to this demand, the field requires not only novel modeling techniques but also advanced control strategies to selectively manipulate these approximations for tangible benefits. This Special Issue is motivated by the pressing need to explore and disseminate advancements in System Modeling, Control Theory, and their diverse applications. We invite authors to contribute research articles that delve into the intricacies of Systems Modeling, Control Theory, and their real-world applications, underpinned by robust mathematical and analytical foundations.

Abstract

Currently, various light-emitting diode (LED) lighting systems are being developed because LEDs are one of the most used lighting sources for work environments, buildings, homes, and public roads in terms of some of their applications. Similarly, they have low energy consumption, quick responses, and excellent optimal performance in their operation. However, these systems still need to precisely regulate lighting, maintain stable voltage and current in the presence of faults and disturbances, and have a wide range of operations in the event of trajectory changes or monitoring tasks regarding the desired voltage and current. This work presents the design and application of two types of robust controllers (structure-at-infinity control and geometric control) applied to an LED driver using a buck converter. The controllers aim to follow the desired trajectories, attenuate disturbances at the power supply input, and compensate for faults in the actuator (MOSFET) to keep the capacitor voltage and inductor current stable. When comparing the results obtained with the two controllers, it was observed that both present excellent performance in the presence of constant disturbances. However, in scenarios in which variable faults and path changes are implemented, the structure-at-infinity control method shows an overimpulse of output voltage and current ranging from 39 to 42 volts and from 0.3 to 0.45 A, with a margin of error of 1%, and it can generate a failure in the LED driver using a buck converter. On the other hand, when using geometric control, the results are satisfactory, achieving attenuating constant disturbances and variable faults, reaching the desired voltage (40 v to 35 v) and current (0.3 to 0.25 A) with a margin of error of 0.05%, guaranteeing a system without overvoltages or the accelerated degradation of the components due to magnetic conductivity.
