This work deals with the novel application of the sliding mode (discontinuous) output regulation theory to a nonlinear electrical circuit, the so-called boost power converter. This theory has excelled due to the fact that trajectory tracking plays a central role. The control of a boost power converter for the output tracking of a DC biased sinusoidal signal is a challenging problem for control engineers. The main difficulties are the computation of a proper reference signal for the inductor current, and the stabilization of the inductor current dynamics or to guarantee the correct output tracking of the capacitor voltage. With the application of the discontinuous output regulation these problems are solved in this work. Simulations and real time experiments were carried out with an unknown variation of the DC input voltage, where the good output tracking of the capacitor voltage was verified along with the stabilization of the inductor current. The discontinuous output regulation theory has proven to be a suitable tool in the output tracking for the boost power converter.

“…[47][48][49] The classic PI and PID controllers make the system have the overshoots and undershoots for a long time and sometimes the damping time of the system is not at an acceptable level. [42][43][44][45][46][47][48][49][50] Furthermore, the amplitude of the output signals at the sudden changes in input voltage or output loads moments with these overshoots and undershoots values are not desired. These controllers need a detailed and accurate mathematical model of the converter and do not advise for the non-linear topologies with uncertain data.…”

Summary PV‐based and wired type of the electrical bicycles (e‐bike) battery charging stations widely is spreading because of the resonant network limitations and low efficiency of the wireless mode for these stations. The generated voltage of many of the PV panels such as JIYANGYIN HR‐200 W‐24 V at the maximum power point is around 36VDC. So, a step‐down converter with a PID controller for Maximum Power Point Tracking (MPPT) of the PV panels is considered between PV panels and boost converter in order to decrease this voltage and enhance the current values for the load side. A sliding mode controller (SMC) equipped with a non‐isolated DC‐DC boost converter with reduced voltage stresses on the power switch is presented. The step‐up converter increases the voltage to the utility level of the e‐bike with around 360 Wh amount of energy. The main concerns about the converters are the efficiency, voltage, and current stresses, number of active or passive components in the converter topology and simplicity. In comparison with a conventional step‐up converter, the selected converter has a lower dynamic loss in the input inductor that can give a proper efficiency by considering its higher voltage gain. The average state‐space model for the SMC is used and the main advantage of the controller is its independency to the inductor current or the amount of the load. The proposed SMC is compared with PID and Fuzzy Logic Controller (FLC) methods and based on the results, the robustness, overshoot, and damping factor of the controller are at an acceptable and better level. All mathematical, simulation and comparison results are presented. A 720 Wh circuit has been implemented for charging all types of the Li‐Ion or Li‐Polymer batteries with 36VDC and 10 Ah specifications.

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.
