“…Within the above fixed interval, in order to limit the current of the Bat in charge and discharge modes, the dynamic thresholds of DC bus reference voltage calculated by the outer voltage loop are defined as follows: The above constraints of Bat current can be summarized as (15) and (16), which are integrated in the anti-windup scheme of the outer voltage loop, in order to prevent the saturation of the integral term.…”

“…Therefore, in order to obtain an approving balance between the control performance and economy, semi-active topology based on a single converter is adopted in this paper. Moreover, several control strategies have been adopted in hybrid power system previously [13][14][15][16][17]. However, the solution of the disturbance rejection is not considered for a single converter based Bat/ SCs system.…”

This paper proposes a robust control strategy for a hybrid battery/super capacitors power system with a single converter. In such systems, it is required to smooth the battery current considering the load power transient and the current oscillations of the DC bus delivered by the load in the context of a hybrid electric vehicle. Furthermore, constraints of all the system components, i.e. maximum current of the battery and super capacitors, state of the charge of the super capacitors and battery temperature should be taken into account. To deal with these demands, a novel cascaded voltage control loop is proposed. For the outer voltage loop, an anti-windup proportional integral controller is used to regulate the super capacitor voltage at its nominal value. On the other hand, for the inner voltage loop, an anti-windup super twisting controller is proposed to ensure the convergence of the DC bus voltage to its reference value while attenuating the external perturbation. Indeed, the specific feature of such controller is that it works like a low-pass filter which leads to attenuate the current oscillations in the DC bus.

“…Among the nonlinear control schemes, sliding mode control (SMC) has been widely reported for renewable energy and power systems applications. SMC methods are reported in [30][31] for DAB converter integrated battery storage system. A sliding mode control scheme based on an average output current model of a DAB converter has been reported in [32].…”

“…Classical SMC method has several disadvantages such as high frequency chattering in control signal and limited switching on a hardware platform. In order to address the aforementioned problems, a double integral sliding mode control (DSMC) is proposed for battery energy storage systems in [33] and the validity was verified experimentally. In [34], a terminal sliding mode control is reported for compensation of perturbation.A sliding mode (SM)-based direct power control (DPC) scheme is proposed and verified experimentally for DAB converter application [35].…”

In this paper, an industrial grade adaptive control scheme is proposed for a micro-grid integrated dual active bridge driven battery management system (DIBMS). A benchmark industrial grade adaptive control scheme depends on two factors namely robustness and computational resource utilization when such controllers are implemented over processors. The mathematical model of DIBMS system is nonlinear, thus for desired response, non-linear controllers based on sliding mode variable structure control theory suits it well for the state regulation problem of DIBMS, however such controllers utilize high computational resources when practically implemented over processors. Keeping in view the above performance indices, this paper proposes an industrial grade computationally efficient and finite time adaptive robust convergent control for DIBMS system. A proportional integral (PI) scheme is used as central control unit and Hebbian algorithm with double integration of the state error is introduced for online tuning the gains of central control unit. The robustness and computational resource efficiency of the proposed control paradigm is validated using a laboratory scale test bench through TI Launchpad (TMS320F28379D). The superiority of the proposed AI based PI control paradigm is compared with classical PI, integer order sliding mode control (SMC), and fractional order SMC (FOSMC) in terms of computational resource utilization and robustness under all test conditions.
