“…The work here reported is an extension of a preliminary analysis reported in [21,22], where a boost converter under SMC and supplying an ideal CPL was reported. In that work, the corresponding theoretical predictions were validated by means of PSIM simulations performed on the detailed switched model.…”

“…In Fig. 4, the points P 1 , P 2 and P 3 are different initial conditions for (i L1 (0), v C1 (0)) selected in such a way that P 1 and P 2 do not accomplish condition (22), therefore the trajectories starting from these points cannot slide until they arrive at the region of ESM. On the contrary, P 3 is selected inside of the ESM region and its trajectory quickly reaches the equilibrium point without any inrush current.…”

“…the inductor current will be equal to the reference value of the current but the capacitor voltage will depend on initial capacitor voltage. Also for certain values of K i1 and K C1 , conditions (22) and (30) cannot be accomplished, consequently, there will be no sliding mode, as in the case of combination 1 in Table 2.…”

“…one surface for start-up and another one for voltage regulation once the converter is enough to close to its steady-state regime. A detailed study of the coefficients of the second switching surface has shown in [22] that the mentioned problem can be correctly solved using only this surface with an appropriate selection of its parameters.…”

The cascade connection of two dc-dc switching converters for constant power supply is studied. The source converter is of boost type while the load converter is of buck type. The natural unstable behaviour of the cascade connection for both ON and OFF states of the boost converter is counteracted by a sliding-mode control strategy that combines unstable trajectories to generate a stable one for the regulated boost converter dynamics. Experimental results using an electronic load to emulate a buck converter-based constant power load are in good agreement with the theoretical predictions. A similar agreement is later obtained when a buck converter with a dynamic behaviour close to an instantaneous constant power load is employed instead of the electronic load.

“…In this context, Sliding Mode (SM) control have been increasingly accepted for controlling power conditioning systems [5][6][7][8][9]. These control techniques proved to be particularly suitable for electronic converters, granting excellent features of robustness and finite-time convergence, which make them highly appropriate for microgrid applications [10][11][12][13][14].…”

Stability Criteria for Input Filter Design in Converters with CPL: Applications in Sliding Mode Controlled Power Systems

Microgrids are versatile systems for integration of renewable energy sources and non-conventional storage devices. Sliding Mode techniques grant excellent features of robustness controlling power conditioning systems, making them highly suitable for microgrid applications. However, problems may arise when a converter is set to behave as a Constant Power Load (CPL). These issues manifest in the stability of internal dynamics (or Zero Dynamics), which is determined by the input filter of the power module. In this paper, a special Lyapunov analysis is conducted to address the nonlinear internal dynamics of SM controlled power modules with CPL. It takes advantage of a Liérnad-type description, establishing stability conditions and providing a secure operation region. These conditions are translated into conductance and invariant region diagrams, turning them into tools for the design of power module filters.

Sliding mode control for fuel cell supported battery charger in vehicle‐to‐vehicle interaction

In typical vehicle‐to‐vehicle (V2V) charging systems, energy transfer is provided from a battery electric vehicle (BEV) to charge the energy storage unit of another BEV. In this study, the utilization of a fuel cell electric vehicle (FCEV) as an energy provider is purposed to charge the energy storage unit of a BEV in V2V interaction. Since FCEVs are filled with hydrogen, it also eliminates the disadvantages of traditional BEV energy providers, such as a reduction in the amount of stored energy and the need for more time to charge fully. In the designed system, a new plug‐in external V2V battery charger topology supported by an FCEV has been proposed to supply electrical energy. In order to control the energy transfer between electric vehicles (EVs), a sliding mode controller is adapted to manage the external converter interface located between vehicles. The designed controller shows improved robustness against the system dynamics uncertainties and disturbances generated by a variety of internal and external causes. In the designed section, a proton exchange membrane fuel cell with the maximum operational rating of 75 kW is used as an energy provider to feed consumer loads. The proposed system has been designed and analyzed for several loading situations from 20% to 100% loading and obtained performance results have been compared with a conventional controlled V2V battery charger system. The case studies validate that the proposed V2V charger system gives better results than the conventional controlled FC‐supported V2V. The stability and robustness of output electrical waveforms are better for the designed system. In this context, the tracking error of the conventional controller is about 8% larger than that of the designed sliding mode control for dynamic load changes. The sliding mode controller has a faster settling time (approximately 0.12 s) in comparison with the conventional controlled V2V charger system. Also, mean absolute error values verify that the designed sliding mode controller operates smoothly under all cases except load transition compared to the typical control method. As a result, the case studies show that satisfactory results have been obtained for the designed system.
