This research introduces an improved control strategy for active power filter (APF) system. It utilizes adaptive super-twisting sliding mode (STSMC) scheme. The proposed approach integrates interval type-2 fuzzy neural network with a self-feedback recursive structure (IT2FNN-SFR) to enhance the overall performance of APF IT2FNN STSMC here consists two components, one being IT2FNN-SFR, which demonstrates robustness uncertain systems and ability utilize historical information. IT2FNN-SFR estimator is used approximate unknown nonlinear function within APF. Simultaneously, component integrated reduce system chattering, improving precision performance. combines simplicity traditional control, effectively addressing chattering problem. To mitigate inaccuracies complexities associated manual parameter setting, law gain formulated achieve optimal solutions. designed framework, facilitating optimization. Experimental validation conducted verify harmonic suppression capability strategy. THD corresponding algorithm 4.16%, by 1.24% 0.55% compared ASMC STSMC, respectively, below international standard requirement 5%. Similarly, controller also advantages in dynamic performance: when load decreases, it 4.72%, outperforming 1.15% 0.38%, respectively; increases, 3.87%, surpassing 1.07% 0.36%, respectively.

This paper addresses cooperative target encircling of multiple autonomous surface vehicles (ASVs) with private and potentially competitive objectives. A fully distributed control approach is proposed based on noncooperative games. Specifically, a estimator an adaptive gain developed to estimate the information without using global state or topology knowledge. Based low-frequency learning technique, fuzzy predictor presented approximate unknown vehicle kinematics induced by uncertain nonlinearities environmental disturbances. By decoupling into task spacing task, law are designed Nash equilibrium seeking for achieving objective each ASV. The input-to-state stability closed-loop system proven via cascade analysis. Simulation results provided illustrate effectiveness game-based method ASVs in circumnavigation missions.
