“…For this study, stability was assured via PCH systems, and controller performance was validated through numerical simulations. In [ 32 ], a PEMFC boost fuel cell system was controlled for output power regulation dealing with the auxiliary units of the EGS (air compressor, air cooler, and water-based heat exchange, among others). The controller was designed with SMC and two nonlinear observers were designed with an extended Kalman filter and a sliding mode observer.…”

In this paper, a passivity-based control (PBC) scheme for output voltage regulation in a fuel-cell/boost converter system is designed and validated through real-time numerical results. The proposed control scheme is designed as a current-mode control (CMC) scheme with an outer loop (voltage) for voltage regulation and an inner loop (current) for current reference tracking. The inner loop’s design considers the Euler–Lagrange (E-L) formulation to implement a standard PBC and the outer loop is implemented through a standard PI controller. Furthermore, an adaptive law based on immersion and invariance (I&I) theory is designed to enhance the closed-loop system behavior through asymptotic approximation of uncertain parameters such as load and inductor parasitic resistance. The closed-loop system is tested under two scenarios using real-time simulations, where precision and robustness are shown with respect to variations in the fuel cell voltage, load, and output voltage reference.

“…An ES technique was utilized by [30] for PEMFC control with respect to constant current and hydrogen influx. State-of-the-art research in the control domain classifies SMC as the best candidate for nonlinear systems with unknown disturbances and load uncertainties, along with the improved transient response [31][32][33]. However, it is only true if implemented through the discontinuous control law, where the switching frequency approaches infinity.…”

Fuel cells guarantee ecological ways of electricity production by promising zero emissions. Proton exchange membrane fuel cells (PEMFCs) are considered one of the safest methods, with a low operating temperature and maximum conversion efficiency. In order to harness the full potential of PEMFC, it is imperative to ensure the membrane’s safety through appropriate control strategies. However, most of the strategies focus on fuel economy along with viable fuel cell life, but they do not assure constant output voltage characteristics. A comprehensive design to regulate and boost the output voltages of PEMFC under varying load conditions is addressed with dynamic integral sliding mode control (DISMC) by combining the properties of both the dynamic and integral SMC. The proposed system outperforms in robustness against parametric uncertainties and eliminates the reaching phase along with assured stability. A hardware test rig consisting of a portable PEMFC is connected to the power converter using the proposed technique that regulates voltage for varying loads and power conditions. The results are compared with a proportional integral (PI) based system. Both simulation and hardware results are provided to validate the proposed technique. The experimental results show improvements of 35.4%, 34% and 50% in the rise time, settling time and robustness, respectively.

“…Some studies [14] that design a double-loop controller based on the proportional-integral (PI) algorithm could solve this issue and the PI controller also has a wide range of applications due to its mature designing process for parameters [15,16]. On the other hand, sliding control is another method used in converters because of its strong robustness 3 [17][18][19], in particular, super-twisting sliding mode (STSM) control is a central issue in recent years, because it reduces the chattering compared with traditional sliding mode control (TSMC) in most cases [20]. Authors of [21] use TSMC in a boost converter to minimize the inrush current with DC power.…”
