K. Zhao, C. Y. Wen, Y. D. Song, and  F. L. Lewis,  “Adaptive uniform performance control of strict-feedback nonlinear systems with time-varying control gain,” IEEE/CAA J. Autom. Sinica, vol. 10, no. 2, pp. 451–461, Feb. 2023. doi: 10.1109/JAS.2022.106064 

> Proposed control is flexible to handle the global or symmetric semi-global performance cases uniformly just by selecting the initial value of the time-varying scaling function properly, making the controller re-design and stability re-analysis not required.

> By defining an ENF and imposing a condition on the update law of Nussbaum argument, the developed control relaxes the complicated calculation and proof in the existing results.

> By extracting the core function information from the non- parametric uncertainty, no approximator is required, despite unknown control directions.

> A novel finite-time distributed identification method is introduced for nonlinear interconnected systems using concurrent learning.

> Concurrent learning approach continually minimizes the identification error for a batch of previously recorded data collected from each subsystem as well as its neighboring subsystems.

> State information of neighboring interconnected subsystems is acquired through direct communication.

> Presents a novel fixed-time stabilization control method for a class of strict-feedback nonlinear systems involving unmodelled system dynamics. 

> Compared with existing results, the ``explosion of complexity" problem of backstepping control is avoided.

> Proposed controller is still valid beyond the given fixed-time convergence instant.

Hu, “Adaptive consensus quantized control for a class of high-order nonlinear multi-agent systems with input hysteresis and full state constraints,” IEEE/CAA J. Autom. Sinica, vol. 9, no. 9, pp. 1574–1589, Sept. 2022. doi: 10.1109/JAS.2022.105800 

> Quantized control method of the hysteretic multi-agent systems is considered and a hysteresis quantization inverse compensator is established.

> First study to apply the barrier Lyapunov function to the hysteretic multi-agent systems.

> Quantized control strategy constructed only requires quantizer to have sector bounded property.

> Decentralized control scheme proposed removes all the two widely adopted traditional conditions of the interconnected terms by using the inherent properties of Gaussian function and thereby deals with completely unknown strong interconnections successfully.

> Asymptotic tracking control is realized even though the uncertain parameters, large-scale system structure and unknown strong interconnections are considered.

> By applying the DSC technology, the inherent “explosion of complexity” problem in backstepping is eliminated.

> An improved T-S fuzzy model is introduced to achieve highly accurate approximation via an affine model under each fuzzy rule.
