Reduced complexity existence conditions for robust L2-gain feedforward controllers for uncertain systems using dynamic IQCs
نویسنده
چکیده
For uncertain systems described in the standard LFT form, we consider the problem of designing robust L2-gain disturbance feedforward controllers if the uncertain blocks are described by integral quadratic constraints (IQCs). For technical reasons related to the feedforward problem we work with the duals of the constraints involved in robustness analysis using IQCs. Based on an elimination of the controller parameters, we develop in this paper reduced complexity LMI conditions for the existence of a stable feedforward controller that guarantees a given L2-gain for the closed-loop system.

Robust H2 switching gain-scheduled controller design for switched uncertain LPV systems
In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
متن کاملConvex LPV synthesis of estimators and feedforwards using integral quadratic constraints
A method is presented for synthesizing output estimators and disturbance feedforward controllers for continuous-time, uncertain, gridded, linear parameter-varying (LPV) systems. Integral quadratic constraints (IQCs) are used to describe the uncertainty. Since gridded LPV systems do not have a valid frequencydomain interpretation, the time-domain, dissipation inequality approach is followed. The...
متن کاملDecentralized Variable Gain Robust Controllers with Guaranteed L2 Gain Performance for a Class of Uncertain Large-Scale Interconnected Systems with State Delays
In this paper, we propose a decentralized variable gain robust controller with guaranteed L2 gain performance for a class of uncertain large-scale interconnected systems with state delays. The proposed decentralized robust controller consists of a fixed gain and a variable gain tuned by parameter adjustment laws. In this paper, it is shown that sufficient conditions for the existence of the pro...
متن کاملRobust H_∞ Controller design based on Generalized Dynamic Observer for Uncertain Singular system with Disturbance
This paper presents a robust ∞_H controller design, based on a generalized dynamic observer for uncertain singular systems in the presence of disturbance. The controller guarantees that the closed loop system be admissible. The main advantage of this method is that the uncertainty can be found in the system, the input and the output matrices. Also the generalized dynamic observer is used to est...
متن کاملRobust H 1 analysis and control of linear systemswith integral quadratic constraints
In this paper, we consider a class of uncertain linear systems which are subject to a general type of integral quadratic constraints (IQCs). Two problems are addressed: 1) robust H 1 analysis and 2) robust H 1 control. In the rst problem, we determine if the system sat-isses a desired H 1 performance for all admissible uncertainties subject to the IQCs. In the second problem, we seek for a dyna...
