This paper proposes a robust algorithm based on fixed-time sliding mode controller (FTSMC) for Quadrotor aircraft. approach is Lyapunov theory, which guarantees system stability. Nonlinear error dynamics techniques are used to achieve accurate trajectory tracking in the presence of disturbances. The performance FTSMC compared with typical non-singular terminal (NTSMC) evaluate its effectiveness...

This paper investigates the appointed-time attitude stabilization problem of a rigid spacecraft under disturbance and parametric uncertainty. A continuous sliding mode observer is presented to observe synthetical term. To circumvent singularity in terminal control, new nonsingular surface designed by employing concept switching control. Based on observation information deriving from proposed ob...

This paper reviews recent automotive applications of sliding mode control. The design methods discussed include sliding mode optimization, integral sliding mode and higher order sliding mode. Examples of applications of conventional sliding mode as well as advanced techniques in vehicle suspension control, engine throttle position control, parameter estimation and fault diagnosis are summarized.

The paper presents some experimental results of a real-time implementation of discrete sliding mode control combined with a fuzzy-logic damper block. The hybrid real-time algorithm developed is aimed at applications to discrete systems. The sliding mode part of the solution is based on system input and output measurements. The algorithm combines an integral action, a nonlinear output feedback, ...

Nonlinear system control has been widely concern of the research. At present, the nonlinear system decoupling control and static feedback linearization that based on the theory of differential geometry brought the research getting rid of limitation for local linearization and small scale motion. However, differential geometry control must depend on precise mathematical model. As a matter of fac...

One of the most important challenges in nonlinear, multi-input multi-output (MIMO) and time variant systems (e.g., robot manipulator) is designing a controller with acceptable performance. This paper focused on design a new artificial non linear controller with on line tunable gain applied in the robot manipulator. The sliding mode fuzzy controller (SMFC) was designed as 7 rules Mamdani’s infer...

Original scientific paper A method for practical implementation of discrete-time sliding mode control technique for control of plants with stable finite zero is proposed in this paper. The method is based on a combination of different conventional and sliding mode control approaches. The control system contains a sliding mode controller, an observer, based on nominal plant model without finite ...

In this paper, the modified optimal sliding mode control with a proposed method to design a sliding surface is presented. Because of the inability of the previous approach of the sliding mode method to design a bounded and suitable input, the new variation is proposed in the sliding manifold to obviate problems in a structural system. Although the sliding mode control is a powerful method to re...
