The Behavioral Approach to Linear Parameter-Varying Systems
IEEE Transactions on Automatic Control, 2011Linear parameter-varying (LPV) systems are usually described in either state-space or input-output form. When analyzing system equivalence between different representations it appears that the time-shifted versions of the scheduling signal (dynamic dependence) need to be taken into account.

Linear parameter-varying descriptions of nonlinear systems
Proceedings of the 2004 American Control Conference, 2004Recent methods for gain scheduling controller design based on linear parameter-varying (LPV) systems offer a systematic way to obtain a nonlinear controller. However, the non-unique LPV description of the nonlinear system is essential for the performance of the design. In this paper, two approaches to obtain LPV descriptions are presented.

Analysis of hybrid linear parameter-varying systems
Proceedings of the 2003 American Control Conference, 2003., 2004This paper proposes a new hybrid linear parameter-varying (LPV) systems and investigates some characteristics of these systems. A hybrid LPV system is defined by a ser of LPV systems and average dwell-time as a model of discrete event dynamics. This system encompasses typical LPV systems and emerging hybrid systems such as reconfigurable flight control.

Cooperative control of linear parameter-varying systems
2012 American Control Conference (ACC), 2012The state consensus problem among groups of linear parameter-varying (LPV) systems is addressed. The systems are assumed to have an identical LPV structure. We consider both homogeneous groups, where the time-varying parameters are identical, and heterogeneous groups, where the parameters can be different for all agents.

An inverse system for linear parameter-varying max-plus-linear systems
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2004The Max-Plus-Linear (MPL) system is a state-space description for a certain class of discrete-event-systems that are-linear in max-plus algebra. This paper considers an extended description of MPL systems with a linear parameter varying structure, which is called LPV-MPL systems, and proposes an inverse system of the LPV-MPL system, which calculates ...

Approximation of linear parameter-varying systems
Proceedings of 35th IEEE Conference on Decision and Control, 2002Two well known LTI approximation methods-balanced truncation and optimal Hankel norm approximation-are extended to the LPV framework. Quadratic stability of the approximants and generalisations of known LTI error bounds are examined. The concept of the graph operator of an LPV system is discussed.

Stabilization of linear parameter varying systems
Proceedings of 32nd IEEE Conference on Decision and Control, 2002Reviews two existing methods for stabilization: small-gain input/output methods and high-gain state space methods. The authors further investigate these methods in the context of possible conservatism and robustness properties. The authors then suggest possible alternative structures for linear parameter varying systems stabilization.

Structured control of affine linear parameter varying systems
Proceedings of the 2011 American Control Conference, 2011This paper presents a new procedure to design structured controllers for discrete-time affine linear parameter-varying systems (A-LPV). The class of control structures includes decentralized of any order, fixed-order output feedback, simultaneous plant-control design, among others.

Subspace identification of multivariable linear parameter-varying systems
Automatica, 2002A subspace identification method is discussed. It deals with multivariable linear parameter-varying state-space systems with affine parameter dependence. To overcome the problem of exponential increase in the number of rows of the data matrices, a selection procedure for reducing their numbers is proposed.

Design and validation of a linear parameter varying localization system
2014 IEEE International Conference on Autonomous Robot Systems and Competitions (ICARSC), 2014This paper proposes and experimentally validates a landmark-based absolute mobile robot localization system, composed by two filters, one for attitude estimation and the other for position estimation. The estimation is carried out in the body-frame allowing for the model kinematics to be LPV (Linear Parameter Varying), thus using no approximate ...
