“…The load at the DC bus is a 3-phase inverter driving a three AC motor [induction motor or permanent magnet synchronous motor (PMSM)], as a vehicle traction drive. So far, algorithms based on differential flatness have been successfully applied to power converters (e.g., 3-phase inverter and rectifier, interleaved boost converter, modular multilevel converter) [17,18,20,21], permanent magnet synchronous motor and AC servomotor [19,22,23]. Based on these previous works, the purpose of this article is to extend the use of differential flatness algorithm in an embedded DC microgrid (i.e., EV powertrain) to manage optimally its operation during static and dynamic operations.…”

“…This approach has enabled the system to be an alternative representative, of which motion planning and regulator tuning is clear-cut. This theory has lately been utilized in a variety of networks in different scientific domains [17][18][19][20][21][22][23]. Compared to the nonlinear algorithm (i.e., sliding mode, Lyapunov, fuzzy logic) reported in [13][14][15], nonlinear algorithms based on differential flatness require the use of trajectory planning to implement the control laws.…”

This article proposes a new control law for an embedded DC distributed network supplied by a supercapacitor module (as a supplementary source) and a battery module (as the main generator) for transportation applications. A novel control algorithm based on the nonlinear differential flatness approach is studied and implemented in the laboratory. Using the differential flatness theory, straightforward solutions to nonlinear system stability problems and energy management have been developed. To evaluate the performance of the studied control technique, a hardware power electronics system is designed and implemented with a fully digital calculation (real-time system) realized with a MicroLabBox dSPACE platform (dual-core processor and FPGA). Obtained test bench results with a small scale prototype platform (a supercapacitor module of 160 V, 6 F and a battery module of 120 V, 40 Ah) corroborate the excellent control structure during drive cycles: steady-state and dynamics.

“…In 1995, the differential flatness approach was proposed by Fliess et al [24]. Based on this work carried out by Fliess et al [24], the differential flatness control strategy has been employed successfully in several works to control power electronics and manage energy flows in embedded applications [25][26][27][28][29][30][31][32]. In [25], the differential flatness control is applied to the unmanned aerial vehicle to solve trajectory planning issues, whereas in [26], this control is used in a stand-alone power supply to manage different sources (i.e., fuel cell (FC), batteries, and SCs) connected to classic converters (i.e., boosts for the FC and buck-boosts for the energy storage devices).…”

“…In comparison, in [27] the authors have employed the differential flatness theory to control an output series interleaved DC-DC boost converter for FC applications, while in [31] it is used to manage a distributed generation hybrid system based on FC and SC connected respectively to four-phase boost and buck-boost converters. In [28][29][30], the control of the AC-DC converter and DC-AC converters supplying permanent magnet synchronous motors is based on a differential flatness approach. Finally, in [32] the control of a two-phase interleaved buck-boost converters connected to energy storage devices (i.e., batteries and SC) and the stability of the DC bus in a hybrid electric vehicle is ensured by the use of this nonlinear control.…”

Differential Flatness Based-Control Strategy of a Two-Port Bidirectional Supercapacitor Converter for Hydrogen Mobility Applications

et al. 2020

This article is focused on an original control approach applied to a transportation system that includes a polymer electrolyte membrane fuel cell (PEMFC) as the main energy source and supercapacitors (SC) as the energy storage backup. To interface the SC with the DC bus of the embedded network, a two-port bidirectional DC-DC converter was used. To control the system and ensure its stability, a reduced-order mathematical model of the network was developed through a nonlinear control approach employing a differential flatness algorithm, which is an attractive and efficient solution to make the system stable by overcoming the dynamic issues generally met in the power electronics networks of transportation systems. The design and tuning of the system control were not linked with the equilibrium point at which the interactions between the PEMFC main source, the SC energy storage device, and the loads are taken into consideration by the proposed control law. Besides this, high dynamics in the load power rejection were accomplished, which is the main contribution of this article. To verify the effectiveness of the developed control law, a small-scale experimental test rig was realized in the laboratory and the control laws were implemented in a dSPACE 1103 controller board. The experimental tests were performed with a 1 kW PEMFC source and a 250 F 32 V SC module as an energy storage backup. Lastly, the performances of the proposed control strategy were validated based on real experimental results measured during driving cycles, including motoring mode, ride-though, and regenerative braking mode.

In hydrogen production, AC‐DC rectifiers must provide a high current and low voltage to the production load. This paper focuses on the efficient performance and elimination of the output ripple in these AC‐DC rectifiers. Unfortunately, efforts to reduce the current ripple often lead to lower efficiency, causing a contradiction. To address this issue, a low‐ripple high‐efficiency AC‐DC rectifier with an auxiliary compensator is proposed in this paper. The proposed rectifier can maximise efficiency while eliminating the current ripple, including the switching ripple and low‐frequency ripple. By incorporating a rectifier‐chopper and a buck circuit with a series‐connected capacitor, the auxiliary compensator, the solution provides an additional flow path for the current ripple at the rectifier output, successfully preventing the ripple from being output to the load. This paper offers a thorough exposition regarding the causative factors and sources of the switching and low‐frequency ripple. Furthermore, a detailed explication of the operating principle of the proposed rectifier system is provided. The losses and costs associated with auxiliary compensators are then analysed for persuasive purposes. Finally, simulation and experimental results verify the feasibility and superiority of the proposed rectifier.
