This paper deals with the design of a moving sliding surface in a variable structure plant for a second order system. The chattering phenomena is also dealt with during the switching process for an unstable sliding surface condition. The simulation examples considered in this paper shows the effectiveness of the sliding mode control method used for the design of the moving sliding surfaces. A s...

This paper deals with the fault ride-through capability assessment of a doubly fed induction generator-based wind turbine using a high-order sliding mode control. Indeed, it has been recently suggested that sliding mode control is a solution of choice to the fault ride-through problem. In this context, this paper proposes a second-order sliding mode as an improved solution that handle the class...

This paper presents a sliding mode filter that effectively removes impulsive noise and high-frequency noise with producing much smaller phase lag than linear filters. It is less prone to overshoot than previous sliding mode filters and it does not produce chattering. In addition, it is computationally inexpensive, and thus suitable for realtime applications. The proposed sliding mode filter emp...

This paper proposes a higher order sliding mode controller for uncertain robot manipulators. The motivation for using high order sliding mode mainly relies on its appreciable features, such as high precision and elimination of chattering in addition that assure the same performance of conventional sliding mode like robustness. Instead of a regular control input, the derivative of the control in...

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...

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...

An adaptive sliding mode control based on two neural networks is proposed in this paper for Quadrotor stabilization. This approach presents solutions to conventional control drawbacks as chattering phenomenon and dynamical model imprecision. For that reason two ANN for each quadrotor helicopter subsystem are implemented in the control loop, the first one is a Single Hidden Layer network used to...

A variable structure controller design for the tip position control of a exible one-link manipulator was presented in [7]. The control torque obtained using this design methodology was subjected to high frequency chattering. This makes it impossible to implement the controller in practice. The absence of a sign(S) function in the control law makes it impossible to implement the boundary layer t...
