Sliding Surface Matched Condition in Sliding Mode Control
نویسندگان
چکیده
In this paper, the recently developed sliding surface matching condition (SSMC) is viewed from a new point that the mismatched uncertain term should satisfy the minimum-phase condition for the nominal system. With this new viewpoint, SSMC is extended to a more general class of system with nonlinear uncertainties. Finally, a numerical example demonstrates the results.

Terminal Sliding Mode Control for Nonlinear Systems with both Matched and Unmatched Uncertainties
In this paper, we extend the sliding mode idea to a class of unmatched uncertain variable structure systems. This method is achieved with introducing a new terminal sliding variable and the finite time stability of proposed method is proved using a new particular finite time condition in both reaching and sliding phases. In reaching phase new sliding mode controller is derived to guarantee the ...

In this paper, a new smooth second order sliding mode control is proposed. This algorithm is a modified form of Super Twisting algorithm. The Super Twisting guarantees the asymptotic stability, but the finite time stability of proposed method is proved with introducing a new particular Lyapunov function. The Proposed algorithm which is able to control nonlinear systems with matched structured u...

متن کاملDesigning fuzzy-sliding mode controller with adaptive sliding surface for vector control of induction motors considering structured and non-structured uncertainties
Induction motors with nonlinear dynamics are superior in terms of size, weight, motor inertia, maximum speed, efficiency, and cost than direct current machines, and hence their control is of great important. The main objective of this paper is to design a fuzzy sliding mode controller in order to control the position of the induction motor including parametric and non-parametric uncertainties b...
