“…Finally, the controllers control actions (namely, the mechanical synchronous speed of the CW, Ω _ = ) are depicted in Figure 11a,b. Such reduction in the wind turbine conversion efficiency can be clearly visualised in the actual rotational speed-torque plane (see Figure 9a), where the operating points do not precisely evolve over the parabola of optimum torque T opt (Ω), given by Equation (19). This, in turn, means that the power extraction is lower than the maximum available power in the wind.…”

The dual-stator winding induction generator (DWIG) is a promising electrical machine for wind energy conversion systems, especially in the low/mid power range. Based on previous successful results utilising feed forward control, in this article, a super-twisting (ST) sliding mode improved control set-up is developed to maximise power extraction during low wind regimes. To accomplish this objective, via constant volts/hertz implementation, a ST controller was designed to command the DWIG control winding, such that the tip-speed ratio is robustly maintained at its optimal value. The proposed super-twisting control set-up was experimentally assessed to analyse its performance and to verify its efficiency in an actual generation test bench. The results showed a fast convergence to maximum power operation, avoiding chattering and offsets due to model uncertainties.

“…In order to deal with these uncertain disturbances, it is obligatory to design a robust control strategy. Due to the fact that the Super Twisting (ST) sliding mode controller is one of the best choices for controlling the perturbed system with uncertainty and unexpected fluctuations, ST is adopted in this paper [40][41][42][43][44][45][46][47].…”

In order to improve the durability and economy of a hybrid power system composed of a battery and supercapacitors, a control strategy that can reduce fluctuations of the battery current is regarded as a significant tool to deal with this issue. This paper puts forwards a disturbance rejection control strategy for a hybrid power system taking into account the degradation of the battery. First, the degradation estimation of the battery is done by the model-driven method based on the degradation model and Cubature Kalman Filter (CKF). Considering the transient and sinusoidal disturbance from the load in such a hybrid system, it is indispensable to smooth the behavior of the battery current in order to ensure the lifespan of the battery. Moreover, the constraints for the hybrid system should be considered for safety purposes. In order to deal with these demands, a cascaded voltage control loop based on a super twisting controller and proportional integral controller with an anti-windup scheme is designed for regulating the DC bus voltage in an inner voltage loop and supercapacitors’ voltage in an outer voltage loop, respectively. The specific feature of the proposed control method is that it operates like a low-pass filter so as to reduce the oscillations on the DC bus.

Proton‐exchange membrane fuel cells have been established as a really promising technology, specially due to their high efficiency and scalability features, additionally to their low pollution emissions. In a typical topology, fuel cell module (FCM) is usually integrated into a hybrid power system, where the FCM is designed to satisfy the main power requirements and reduce the current ripple at the fuel cell output. In this framework, the aim of this paper is to analyze and design a sliding mode control (SMC) for a FCM based on an isolated phase‐shifted full bridge converter. This particular topology provides a high conversion ratio and attains a reduction of switching losses, which allow its application in low and medium power systems. From the control viewpoint, the proposed module represents a challenge due to the highly nonlinear behavior and wide operation range of the FCM, together with system parameter uncertainties and perturbations. To solve these issues, a second‐order sliding mode super‐twisting algorithm (STA) is proposed. As its main advantage, the STA reduces significantly the control chattering while preserving several features of conventional SMCs, such as robustness and finite time convergence. In order to analyze the zero dynamics stability, a Lyapunov study is proposed, taking advantage of its particular Liérnad‐type system structure. Finally, the designed algorithm is thoroughly analyzed and validated by computer simulation on a commercial 10‐kW FCM and compared to first‐order SMC.
