Discrete time sliding mode control with minimal quasi sliding mode band
2012 12th International Workshop on Variable Structure Systems, 2012A new approach is presented to analyze sliding mode control in discrete-time systems using an established reaching law, whereby the ultimate band is obtained to be lesser than any previous analysis done with the same reaching law. Also, the controller parameters are evaluated according to the ultimate band that is desired.

Reduction of the reaching mode by the sliding mode control with time-varying sliding surface
2015 IEEE/SICE International Symposium on System Integration (SII), 2015In this paper, a sliding mode control method with time-varying sliding surface is proposed. The greatest characteristic of sliding mode control is its robustness against uncertainties, such as disturbances, modeling error, or parameter variation. Robustness is guaranteed only if uncertainties satisfy the matching condition, so it is important to ...

Discrete-Time Sliding-Mode Control With Improved Quasi-Sliding-Mode Domain
IEEE Transactions on Industrial Electronics, 2016In this paper, a new discrete reaching law with improved quasi-sliding-mode domain (QSMD) is proposed and a sliding-mode controller is designed for discrete-time systems with uncertainties. By redefining the change rate as the second-order difference of the system uncertainties and adopting the continuous-approximate function, smaller width of the QSMD

Sliding-Mode Control Variations
IEEE Transactions on Automatic Control, 2007The purpose of this paper is to present a framework in which high-order control variations are employed in sliding mode control to modify the sliding dynamics and/or reduce the dimension of the sliding surface. Control variations are implemented as sampled data feedback controllers with the variations generated during the sample intervals.

A general class of sliding surface for sliding mode control
Proceedings of 35th IEEE Conference on Decision and Control, 1998Sliding control of linear plants is discussed when the relative degree of the chosen sliding surface is greater than one. The asymptotic stability of the system is examined.

Invariant sliding sectors for discrete sliding mode control
Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002A new concept, "invariant sliding sector", for the design of discrete sliding mode control (DSMC) is proposed. The construction of the first order invariant sliding sectors for the second order DSMC systems is first presented, followed by an extension of the first order sector concept to higher order DSMC systems by developing a recursive structure ...

Uniform sliding mode controllers and uniform sliding surfaces
IMA Journal of Mathematical Control and Information, 2012Summary: We propose two uniform Sliding Mode Controllers (SMCs) for a second-order uncertain system. They provide convergence to an arbitrarily small vicinity centered at the origin in finite time, which can be bounded by some constant independent of the initial conditions and uncertainties.

An adaptive fuzzy sliding-mode controller
IEEE Transactions on Industrial Electronics, 1998This paper deals with a new adaptive fuzzy sliding-mode controller and its application to a robot manipulator arm. The theory for this approach and for the heuristics-based linguistic adaptation is presented, and a mathematical description is derived. Furthermore, an application of this adaptive controller for a two-link robot arm is shown.

Sliding mode control for LPV systems
2016 American Control Conference (ACC), 2016LPV models are extremely appealing, as they allow describing the dynamics of many physical systems that are of interest in various engineering applications. For such systems, dedicated control approaches have been proposed, which rely on the measurement of the scheduling variables and exploit such information for improving the closed-loop performance ...

Fuzzy sliding mode controller design with fuzzy sliding mode observer
2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002This paper addresses the design strategy of a decoupled fuzzy sliding mode controller and a fuzzy sliding mode observer on the basis of the Takagi-Sugeno's (T-S) fuzzy model. A class of fourth-order systems such as a cart-pole system could be well controlled and observed in both the pole hyperplane and the cart-hyperplane simultaneously by the proposed
