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...
متن کاملRobust Controller Design Based on Sliding Mode Observer in The Presence of Uncertainties and Actuator Saturation
This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...
متن کاملRobust $mathcal{H}_infty$ Observer-Based Controller for Lipschitz Nonlinear Discrete-Time Systems with Parameter Uncertainties
This note focuses on the design of an observerbased controller for a class of Lipschitz nonlinear discretetime systems with parameter uncertainties. Thanks to the reformulated Lipschitz property [1] that take into account all the properties of the nonlinearities of the system combined with some mathematical tools, it is shown that the solution of the discrete-time output feedback problem, expre...
متن کاملRobust discrete-time nonlinear sliding mode state estimation of uncertain nonlinear systems
In this paper, we propose a discrete-time nonlinear sliding mode observer for state and unknown input estimations of a class of single-input/single-output nonlinear uncertain systems. The uncertainties are characterized by a state-dependent vector and a scalar disturbance/unknown input. The discrete-time model is derived through Taylor series expansion together with nonlinear state transformati...
