The globally observed trend toward electrically supplied devices is common in the transportation segment. Traditionally, the performance of electrical insulation has been assessed with respect to electric stresses and endurance. In all current-carrying devices, magnetic fields will also be superimposed on electric ones; therefore, the influence of a magnetic field's exposure on partial discharge (PD) dynamics is an actual research topic. This problem is important in the T This article has been accepted for publication in IEEE Transactions on Transportation Electrification.

“…When optimizing control for a certain parameter, the influence of other parameters on the control effect is ignored, resulting in a large gap between the final control effect and the theoretical design. Therefore, when controlling the transmission converter, it is necessary to fuse multiple control parameters to achieve the balanced coordinated optimization of control parameters [5]. In this regard, this paper proposes a new passive control strategy for transmission converters by combining the improved ant lion algorithm.…”

At present, the conventional flexible DC transmission converters mainly track the internal energy through sliding mode control or PI control. Due to the lack of dynamic adjustment of controller parameters, the control effect is poor. For this reason, a passive control technology for flexible DC transmission converters based on an improved ant lion algorithm is proposed. The passive controller is designed by constructing the energy storage function. The ant lion algorithm is used to dynamically solve the optimal parameters of the passive controller, and the control process is optimized by adjusting the transition time and overshoot. In the experiment, the control performance of the designed passive control method is tested. The final results can prove that the proposed method has a fast convergence speed of energy function and an ideal passive control effect when it is used to control the transmission converter.

SummaryIn this paper, a dynamic sliding‐mode variable‐structure control (VSC) is proposed for the voltage tracking control for DC‐DC boost converters, combining with a type of fuzzy neural networks (FNNs) based on different membership functions. In terms of the uncertainties from parameter perturbations and unmodeled dynamics in the DC‐DC converter, the FNNs including, respectively, Gaussian membership functions and ellipsoidal‐type membership functions are employed to approximate the uncertainties. Based on an average model for the present converter, a novel dynamic VSC that is induced by an auxiliary dynamics of the duty cycle is designed, by exploring an ideal line sliding surface based on the reference inputs and the duty cycle for the converter. Under the basis of the adaptive FNN dynamic VSC law, the tracking error system of the DC‐DC boost converter is analyzed to be boundedly stable. Eventually, the validation and the superiority of the proposed dynamic VSC method are shown in some comparative simulations.
