This paper investigates the possible adoption of a fractional order sliding surface for the robust control of perturbed integer-order LTI systems. It is proved that the standard approach used in Sliding Model Control (SMC) cannot be used and a substantial redesign of the control policy is needed. A novel control strategy is discussed, ensuring that the sliding manifold is hit at an infinite suc...

In this paper, a sliding mode fuzzy controller for a nonholonomic wheeled mobile robot is proposed for tracking desired trajectories. We know that sliding mode control can deal with non linearities of control system and is robust. However, it has drawbacks such as a chattering. So, we introduce a fuzzy logic in order to reduce this phenomenon. Two sliding mode fuzzy controllers (SMFC) are descr...

This paper presents a novel sliding mode control algorithm for an nth order nonlinear system suffering from parameters uncertainty and subjected to external perturbation. Using the proposed approach, the system will be on the sliding surface at the initial time (t=0). The idea is to eliminate the reaching phase and hence, a considerable amelioration of system robustness can be achieved. Moreove...

In this paper, we will propose a cooperative control approach that is based on the hybrid grey-neural network with sliding mode control (HGNS) methodology. The main purpose is to eliminate the chattering phenomenon such that the two-link robotic manipulator has a superior tracking response. Moreover, the system performance obtained via the method of the HGNS can be improved. In the present appr...

An adaptive sliding mode controller is presented for a class of Single Input Single Output (SISO) nonlinear systems with external disturbance. The designed controller, resulting from the combination of the Classical Sliding Mode Control technique (CSMC), the Proportional Integral controller (PI) and the Proportional Derivative controller (PD), can reduce the chattering phenomenon and guarantee ...

This paper studies the distributed average tracking problem for multiple time-varying signals generated by linear dynamics, whose reference inputs are nonzero and not available to any agent in the network. In the edge-based framework, a pair of continuous algorithms with, respectively, static and adaptive coupling strengths are designed. Based on the boundary layer concept, the proposed continu...
