Robust Discrete-Time Sliding Mode Control of Vehicle Steering System with Uncertainty

Robust Integral Sliding-Mode Control of an Aerospace Launch Vehicle

An analysis of on-line autonomous robust tracking controller based on variable structure control is presented for an aerospace launch vehicle. Decentralized sliding-mode controller is designed to achieve the decoupled asymptotic tracking of guidance commands upon plant uncertainties and external disturbances. Development and application of the controller for an aerospace launch vehicle during a...

Discrete-time sliding mode control for MR vehicle suspension system

Discrete-time fuzzy sliding mode control for a vehicle suspension system featuring an electrorheological fluid damper

This paper presents real-time control characteristics of an electrorheological (ER) suspension system via a fuzzy sliding mode control algorithm which is formulated in a discrete-time manner by considering the sampling rate of an electronic control unit for a vehicle system. A quarter-vehicle system consisting of sprung mass, spring, tire and a cylindrical ER damper (shock absorber) is construc...

Robust Perfect Tracking Control With Discrete Sliding Mode Controller

The closed-loop transfer function of a plant controlled with a classical feedback controller, depends on the dynamics of the plant. Since most feedforward tracking controllers are designed based on this closed-loop transfer function, they are not robust against plant model uncertainties. Sliding-mode controllers have the property that when the system is on the switching line, the closed-loop be...

Dynamic sliding mode control of a four-wheel skid-steering vehicle in presence of sliding

The paper deals with the design and the implementation of a robust path-following feedback controller, based on the dynamic model of a four-wheel skidsteering robot, performing high speed turns. The control inputs are respectively the linear velocity and the yaw angle. The main object of this paper is to elaborate a sliding mode controller, proved to be robust enough to avoid the knowledge of t...
