In conventional sliding-mode control systems, the sliding-mode motion is of reduced order. Two main problems hindering the application of the sliding-mode control are the singularity in terminal slidingmode control systems and the chattering in both the conventional linear sliding-mode and the terminal sliding-mode control systems. This paper proposes a chattering-free full-order terminal-slidi...

, Abstract: This paper proposes a combined fuzzy adaptive slidingmode voltage controller (AFTSMC) for a three-phase UPS inverter. The proposed AFTSMC encapsulates two control terms: a fuzzy adaptive compensation control term, which solves the problem of parameter uncertainties, and a sliding-mode feedback control term, which stabilizes the error dynamics of the system. To extract precise load c...

Recently, sliding mode control method has been extended to accommodate stochastic systems. However, the existing results employ an assumption that may be too restrictive for many stochastic systems. This paper aims to remove this assumption and present in terms of LMIs a slidingmode control designmethod for stochastic systems with state delay. In some cases, the proposed method provides a contr...

General features of finite-time-stable (FTS) homogeneous differential inclusions (DIs) are investigated in the context of slidingmode control (SMC). The continuity features of the settling-time functions of FTS homogeneous DIs are considered, and the system asymptotic accuracy is calculated in the presence of disturbances, noises and delays. Performance of output-feedback multi-input multi-outp...

This paper presents the design of fuzzy sliding mode control algorithm to achieve the specified trajectory tracking on mechatronic arms. The tracking paths are composed of a set of sequentiallyoperated piecewise sliding surfaces which the system’s state can follow to the equilibrium point in phase plane and from which the total tracking time can be obtained directly. It is shown that each fuzzy...

Nowadays, the major advancements in the control of motion systems are due to the automatic control theory. Motion control systems are characterized by complex nonlinear dynamics and can be found in the robotic, automotive and electromechanical area, among others. In such systems it is always wanted to impose a desired behavior in order to cope with the control objectives that can go from veloci...

This paper dealswith the robust control strategy formulti-axis coordinatedmotion system. Firstly, the adjacent cross-coupling error control method was introduced to reduce the synchronization error. Then, the slidingmode control (SMC) lawbasedon themathematical model of the plant was adopted for restraining parameter perturbation. Furthermore, addressing the unknown torque disturbance, a distur...

The problem of sliding-mode control for a class of neutral delay systems with uncertainties in both the state matrices and the input matrix is considered. By selecting a sliding surface depending on the current state and delayed state, the paper gives a sufficient condition in terms of linear matrix inequalities (LMIs) such that the closed-loop system is guaranteed to be asymptotically stable. ...

It is generally very difficult to make effective obstacle avoidance for mobile robots, especially in uncertain environments. This article models the obstacle avoidance problem as a nonlinear sliding mode, using the self-learning method of non-linear system. First, a sliding mode algorithm is proposed for state dependent layers of the mobile robots, in which two kinds of boundary layers are incl...
