Resilient cyber physical infrastructure for single‐phase dual inverter with sliding mode control

Abstract

Summary As the need in cyber infrastructure for electrical systems to realize the industry 4.0 revolution, this paper presents a configuration of two‐switch dual‐output voltage source inverter with integral sliding mode control (ISMC) and cyber twin approach to realize the performance of the system. The inverter has the capability of supplying two independent loads of equal voltage at the load end. The virtual model (cyber twin) is developed to realize the operation of the inverter (physical device) with a host system. The cyber‐physical test bench is developed to evaluate the performance of the physical model (inverter prototype) with cyber‐physical capabilities. The coupled computation of the virtual model and prototype model is executed to analyze the performance of the inverter.

Continuous finite‐time control of four‐leg inverter through fast terminal sliding mode control

“…According to Table , the proposed method shows a lower THD% value and fast dynamic response. Although Reference provides a bit lower THD% value, it uses additional resonant controllers parallel with the SMC to improve the THD%.…”

“…Usually, these methods suffer from complex design and sometimes they are sensitive to model parameters. Sliding mode control (SMC) method is another nonlinear method especially applicable for power electronics converter that was applied to single‐ and three‐phase inverters . The SMC method is highly robust against external disturbances and model parameter uncertainties, simple digital implementation, and suitable and precise regulation over spread span of operation …”
