“…An adaptive sliding-mode strategy was used for getting robust design by removing the bounded uncertainties/perturbations for a USV based surge speed and heading control problem in Tian et al, (2022). Chen et al, (2022) designed an adaptive fuzzy controller for parametric optimization with SMC for a class of switching power converters suited for renewable energy systems . The objective of the current article is to propose an optimal ASMC for a WF approximated nonlinear system.…”

This work presents an optimization-based robust Adaptive Gain Sliding Mode (AGSM) controller for a nonlinear system where wavelet-based approximation technique is employed in contrary to the linearization technique. To find out the mother wavelet corresponding to the best approximation of nonlinear model, Minimum Description Length (MDL) criterion is utilized. Three different wavelet series are considered to find the best mother wavelet function. The constant of the sliding surface follows dynamical adaptive nature using Harmony Search Algorithm (HSA) based optimization technique to mitigate the extent of chattering. On the other hand, the gain adaptation method is used to calculate the gain of the switching control law of Sliding Mode Control. To ensure the stability of the closed-loop system with adapted gain as well as optimal sliding constants, Lyapunov Stability Criterion is exploited. To validate the performance of the proposed controller (Optimal AGSM Controller) in real time, an Inverted Pendulum System is taken with its wavelet approximated model. The results obtained from simulation as well as hardware validate the efficacy of the proposed design with the assurance of handling unbounded disturbances, parametric uncertainties, and chattering.

“…In [ 17 ], the backstepping method was combined with sliding mode control theory, which overcomes the strong dependence of the traditional backstepping method on the system model and shows strong resistance to input and load disturbances. In [ 18 ], a method combining adaptive fuzzy control and sliding mode control was adopted, which significantly improves the system performance. In [ 19 ], a double integral indirect sliding mode control strategy was proposed to effectively eliminate the state error in the output and improve the dynamic performance of the full-bridge circuit.…”

With the continued development of the new energy vehicle industry, two-stage isolated AC/DC converters are widely used because of their simple topology and easy control characteristics. In this study, we investigate the front-stage Buck power factor correction (PFC) converter and rear-stage full-bridge converter. The main circuit design and component selection were completed through a detailed analysis of the circuit characteristics. In terms of the control strategy, the front-stage adopting PI control and parameter adaptive terminal sliding mode control strategy were proposed for the rear-stage full-bridge converter. This new compound control strategy ensures an optimal regulation of the system under different operating conditions. Simulation analysis verified the correctness of the system topology and control strategy. Based on an analysis of the main parameters of the system, a low-power experimental prototype was trial-produced. The experimental results show that under the same load switching conditions, the parameter-adaptive terminal sliding mode control enhanced faster dynamic regulation and stronger robustness than the conventional PI control. The study is also a good reference in terms of engineering work.
