This paper proposes an extended state observer (ESO)-based second-order sliding mode control (SMC) for dynamic voltage restorers (DVRs). Unlike the conventional first-order SMC and some (SOSMC) methods that suffer from chattering, proposed method can alleviate chattering achieve finite-time convergence. Chattering suppression (i.e. eliminating discontinuities) is achieved via continuous input w...

A spatially distributed form of a second-order sliding-mode control algorithm is suggested for the feedback control of a heat process subject to unmeasurable, sufficiently smooth, persistent disturbances of arbitrary shape. In order to obtain a continuous control input, while retaining similar properties of robustness as those usually endowing the discontinuous control systems, a dynamic input-...

Nonlinear control of the squirrel induction motor is designed using sliding mode theory. The developed approach leads to the design of a sliding mode controller in order to linearize the behaviour of an induction motor. The second problem described in the paper is decoupling between two physical outputs: the rotor speed and the rotor flux modulus. The sliding mode tools allow us to separate the...

an asymptotically stable direct adaptive fuzzy pi sliding modecontroller is proposed for a class of nonlinear uncertain systems. in contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.moreover, a pi control structure is used to attenuate chattering. the approachis applied to stabilize an open-...

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...
