“…This calls for implementation of a novel electric power distribution topology. While designing the electric power system (EPS) for More Electric Aircrafts, the following points need to be considered: choice of electric power system architecture (Barzkar and Ghassemi, 2020; Alexander et al , 2018; Jiao et al , 2020; Wang et al , 2019; Chen et al, 2018; Martínez et al , 2022; Cano et al , 2021; Madonna et al , 2018; Zhu et al , 2021; Brombach et al , 2012; Lawhorn et al , 2018; Ghassemi and Saghafi, 2022); choice of power electronic converters for the chosen EPS architecture (Patnaik et al , 2022; Gu et al , 2020; Harikumaran et al , 2021; Nøland et al , 2019; Ni et al , 2019; Clements and Jones, 2018; Buticchi et al , 2018; Vishal et al , 2022); choice of auxiliary energy source (Ansell, 2022; Wu and Li, 2014; Rajashekara and Jia, 2016; Chen and Song, 2019; Bradley, 2022; Geliev et al , 2019; Kreutzer et al , 2016; Dai et al , 2017; Yu et al , 2022; Kreutzer et al , 2018; Fei et al , 2021); and choice of control scheme for the efficient use of primary and auxiliary energy sources (Wen and Zheng, 2018; Kumar et al , 2017; Pandey et al , 2020; Wang et al , 2016; Zhang et al , 2020; Jangir et al , 2017; Xu et al , 2016; Kumar et al , 2017; Karthikeyan and Gupta, 2015; Wang et al , 2015). …”

Purpose The purpose of this paper is to implement a closed loop regulated bidirectional DC to DC converter for an application in the electric power system of more electric aircraft. To provide a consistent power supply to all of the electronic loads in an aircraft at the desired voltage level, good efficiency and desired transient and steady-state response, a smart and affordable DC to DC converter architecture in closed loop mode is being designed and implemented. Design/methodology/approach The aircraft electric power system (EPS) uses a bidirectional half-bridge DC to DC converter to facilitate the electric power flow from the primary power source – an AC generator installed on the aircraft engine’s shaft – to the load as well as from the secondary power source – a lithium ion battery – to the load. Rechargeable lithium ion batteries are used because they allow the primary power source to continue recharging them whenever the aircraft engine is running smoothly and because, in the event that the aircraft engine becomes overloaded during takeoff or turbulence, the charged secondary power source can step in and supply the load. Findings A novel nonsingular terminal sliding mode voltage controller based on exponential reaching law is used to keep the load voltage constant under any of the aforementioned circumstances, and its performance is contrasted with a tuned PI controller on the basis of their respective transient and steady-state responses. The former gives a faster and better transient and steady-state response as compared to the latter. Originality/value This research gives a novel control scheme for incorporating an auxiliary power source, i.e. rechargeable battery, in more electric aircraft EPS. The battery is so implemented that it can get regeneratively charged when primary power supply is capable of handling an additional load, i.e. the battery. The charging and discharging of the battery is carried out in closed loop mode to ensure constant battery terminal voltage, constant battery current and constant load voltage as per the requirement. A novel sliding mode controller is used to improve transient and steady-state response of the system.

“…The advantage of the variable structure control with the sliding mode is the robustness against changing parameters or system disturbances, [7]. Much research has proved that sliding mode control (SMC) has become a robust and efficient control with power electronics converters,[8, 16,17]. The present paper aims to develop a SMC for controlling the inductor current of the buck converter in order to protect the load from strong currents and bad use, especially in the case of charging the battery or supercapacitor.…”

This paper deals an experimental validation of a nonlinear controller using a sliding mode control (SMC) with integral action for a dc-dc buck power converter. The main control objectives are: i) perfect regulation of inductor current with unknown load resistance variation, ii) and ensure the asymptotic stability of the closed-loop system. To this end, a SMC with integral action is elaborated. Using Matlab-Simulink software, numerical simulations are carried out to show the effectiveness of the proposed approach. Furthermore, using an experimental test bench, the real-time controller is developed based on the Dspace 1104 card in real time (RT). It was shown, using formal analysis, simulations and experiments, that the controller achieves all desired performances.
