“…The main drawback is not stable for non-linear systems, the rise time is high, and voltage regulation is affected during the overshoot period [39]. The sliding mode control strategy is the simple approach to robust control.Adaptive intelligent global sliding mode control for the tracking control of a DC-DC converter [40].The main aim of this controller is to model a single boost converter with a high voltage gain for lighting solicitations. Hence, the converter is needed to work in the DCM-CCM boundary to decrease device recovery losses and increase the overall efficiency [41].…”

The DC microgrids (MGs) are receiving more consideration due to growing DC loads. The importance of DC microgrids related to traditional AC distribution is reviewed in detail. Since microgrids are meaningly more energy efficient when executed with distributed generation.The role of power converters is important in the microgrid operations like voltage boost and conversions. A collection of non-isolated DC-DC high voltage gain converters for DC microgrid is discussed here. Also, the architecture of the microgrid is presented in detail. The power flow among distributed resources and load devices in microgrids has to be properly regulated. Considering this issue, the different control structures are discussed in this article.

“…In addition, the cost of periodic equipment maintenance is reduced. Among the proposed solutions to reduce chattering and improve SMC performance, we find terminal SMC (TSMC) technique [8], synergetic control [9], integral SMC (ISMC) strategy [10], fast TSMC technique [11], adaptive global SMC control [12], total SMC [13], nonsingular TSMC [14], fast TSMC technique [15], and fast integral TSMC [16].…”

Traditional direct field-oriented control (DFOC) techniques with integral-proportional (PI) controllers have undesirable effects on the power quality and performance of variable speed contra-rotating wind power (CRWP) plants based on asynchronous generators (ASGs). In this work, a commanding technique based on the DFOC technique for ASG is presented on variable speed conditions to minimize the output power ripples and the total harmonic distortion (THD) of the grid current. A new DFOC strategy was designed based on third-order sliding mode (TOSM) control to minimize oscillations and the THD value of the current and active power of the ASG; the designed technique decreases the current THD from ASG and does not impose any additional undulations in different parts of ASG. The designed technique is simply implemented on traditional DFOC techniques in variable speed DRWP systems to ameliorate its effectiveness. Also, the results show that by using the designed TOSM controllers, in addition to regulating the active and reactive powers of the ASG-based variable speed CRWP system, the THD current and active power undulations of the traditional inverters can be minimized simultaneously, and the stator current became more like a sinusoidal form.

“…Stemming from the desirable merits of SMC approaches, such as fast dynamic response, good transient performance, stability, and robustness to matched parameter uncertainties, it has established itself as one of the most effective strategies to deal with different linear and nonlinear control problems [16][17][18][19]. In this regard, due to the highly nonlinear behavior of WECSs, power control and performance enhancement of these systems have been the topic of many SMC-based control strategies during the past decade [20][21][22].…”

This work presents a nonlinear control approach to maximise the power extraction of wind energy conversion systems (WECSs) operating below their rated wind speeds. Due to nonlinearities associated with the dynamics of WECSs, the stochastic nature of wind, and the inevitable presence of faults in practice, developing reliable fault-tolerant control strategies to guarantee maximum power production of WECSs has always been considered important. A fault-tolerant fractional-order nonsingular terminal sliding mode control (FNTSMC) strategy to maximize the captured power of wind turbines (WT) subjected to actuator faults is developed. A nonsingular terminal sliding surface is proposed to ensure fast finite-time convergence, whereas the incorporation of fractional calculus in the controller enhances the convergence speed of system states and simultaneously suppresses chattering, resulting in extracted power maximisation by precisely tracking the optimum rotor speed. Closed-loop stability is analysed and validated through the Lyapunov stability criterion. Comparative numerical simulation analysis is carried out on a two-mass WT, and superior power production performance of the proposed method over other methods is demonstrated, both in fault-free and faulty situations.
