Anti-Chattering Strategy using Twisting Controller

Hydraulic anti-lock, anti-skid braking system using fuzzy controller

To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

Dynamic Output Feedback Sliding Mode Controller Design for Chattering Avoidance

For a class of linear MIMO uncertain systems, a dynamic output feedback sliding mode control algorithm that avoids the chattering problem and high gain control is proposed in this paper. Without using any differentiator, we develop a modified asymptotically stable second order sliding mode control law in which the developed controller can guarantee the finite time convergence to the sliding mod...

Variable Structure Load Frequency Controller: Optimal Design and Chattering Reduction using Particle Swarm Optimization Algorithm

 This paper presents an optimal design of Variable Structure Load Frequency Controller using Particle Swarm Optimization Algorithm. The optimal design provides a simple systematic way for obtaining optimum feedback gains and switching vector for VSC. It also includes a new method to reduce the chattering associated with the Variable Structure Controllers (VSC). The proposed method has been app...

Lyapunov-design for a super-twisting sliding-mode controller using the certainty-equivalence principle

In this article, a Lyapunov-based control concept is presented combining variable structure and adaptive control. The considered system class comprises single-input systems which are affected by structured and unstructured uncertainties. The design is based on a Lyapunov function for the super-twisting algorithm. This Lyapunov function is exploited to derive the adaptive part of the proposed co...
