Adaptive sliding mode control for unknown uncertain non-linear systems with variable coefficients and disturbances

Sliding Mode Control is one type of robust control, but the classical method often requires prior knowledge of the uncertainties. This study presents a new adaptive sliding mode control method, which can handle the control problem for unknown uncertain non-linear systems without prior knowledge. Furthermore, it can make the state error of different systems converge at the same boundary. Two illustrative examples are presented to highlight the main features of the approach after five systems with complex disturbances are taken as cases to show the applicability of the proposed method.& COPY; 2023 Elsevier B.V.

Automated summary

Sliding Mode Control is a type of robust control method, and this study proposes a new adaptive sliding mode control method that can handle the control problem for unknown uncertain non-linear systems without prior knowledge. The method can also ensure state error convergence at the same boundary for different systems. Two illustrative examples are presented to demonstrate the main features and applicability of the proposed method.
