Design a Robust Powering 5G Telecommunication System Based-Sliding Mode Control

Abstract

Compared to the previous communication networks, 5G networks provide safe and ultra-reliable connections and enable much more reliable communication with shorter response times, higher data speeds, and a much larger number of simultaneous users. With the growth of the utilization of 5G technology in several applications, the challenges of these power networks will also increase. The power plant in the 5G systems includes several converters feeding dc loads. Most of the loads in the 5G power plant behave as a constant power load (CPL). Due to the negative impedance specifications of CPLs, the stability of such a power electronic converter is threatened when feeding the nonideal CPLs. In response to this challenge, eliminating the destructive effect of these CPLs in the 5G systems is a necessity. To stabilize the voltage of the dc–dc converter feeding CPLs in the 5G systems, this article presents a model-free nonsingular terminal sliding-mode control (MFNTSMC) with a single input interval type-2 fuzzy logic control (SIT2-FLC) to solve the instability problem of the power electronic converters feeding CPLs in the 5G systems. The hardware-in-the-loop tests are accomplished to verify the accuracy of the MFNTSMC based SIT2-FLC suggested controller against the instant changes of the CPL power.
