“…Among them, the SMC controller demonstrated optimal performance in terms of undershooting and response time. For the SMC control algorithm, Samantaray J [65] and Huerta-Moro S [66] implemented the SMC algorithm for controlling Si-type switching devices in low-power DC/DC circuits. The output of the experimental circuit falls into the low-frequency low-power range.…”

Arc plasma, characterized by its high current density, high energy concentration, and elevated gas enthalpy, is widely utilized in fields such as metallurgy, chemical industry, energy and environmental protection, as well as aerospace. Plasma treatment of solid waste is one of the advanced environmental protection technologies at the international forefront. The rapid development of plasma technology has led to continuous updates and upgrades of arc plasma power sources. This paper provides a comprehensive review of the research progress in arc plasma technology in China, with a particular focus on two key aspects: structure and control methods. The objective is to provide a novel perspective and insights for the international academic community, thereby driving further development in the field of arc plasma power sources.

In power systems, DC/DC converters are used to reduce or improve the dc voltage level. A dc/dc converter's major difficulty is controlling the output dc voltage closer to the desired set-point voltage at the load and input voltage fluctuation. Designers aim for better efﬁciency, reduced harmonics, and higher power while keeping converter size and power under safe limits. Several control techniques are used in dc/dc converters to overcome the problems mentioned above. This paper compares the transient performance of three control techniques, namely proportional-integral-derivative (PID) control, fuzzy logic control (FLC), and sliding mode control (SMC) methods, after a brief introduction of these techniques. Secondly, the three techniques have performed simulation results of a buck converter feeding a resistive load. Comparative analyses are presented for various conditions such as input voltage and load variation tests. It is observed that SMC outperforms the other two methods for both simulation scenarios.

“…However, a switch condition first have to determine and there is no significant improvement on the input variations or disturbances [3] [4]. Recently, to get superior static and dynamic performances, various control methods were developed, such as hysteresis control, slidingmode control, fuzzy control, etc [5][6][7][8][9][10]. As an attempt to obtain excellent performances, the law of energy conservation, which states that the total amount of energy in a system is constant, has been introduced into the control field.…”

The previously developed control methods based on the conservation of energy in circuits require the accurate estimation of energy losses, which is difficult to measure and calculate for boost converters. Consequently, there always exist steady-state errors in the output voltage if neglecting such circuit energy losses. To address this issue, an improved energy balance control (IEBC) method is proposed in this paper by integrating a simplified energy balance controller (SEBC) with a PI controller. The proposed IEBC can reduce the steady-state output voltage errors without requiring the estimation of circuit energy losses. Furthermore, the proposed IEBC can operate in both the continuous current mode (CCM) and the discontinuous current mode (DCM), thus accurate static and fast dynamic performances are achieved over the entire load operation range. Moreover, the stability of the IEBC is proved using the Lyapunov stability criterion. Compared with that of the SEBC, both simulations and experiments validate the feasibility and robustness of the proposed IEBC method.
