Linear Parameter-Varying Control of Complex Mechanical Systems
IFAC Proceedings Volumes, 2014In standard linear fractional representation (LFR)-based linear parameter-varying (LPV) modeling the size of the (diagonal) scheduling block depends on the number of scheduling parameters and their repetitions, which in turn influences both the complexity of synthesis conditions and the computational load during online implementation of LPV controllers.

Modeling and Identification of Linear Parameter-Varying Systems
2010This book aims to bridge the gap between Linear Parameter-Varying (LPV) modeling and control by investigating fundamental questions of modeling and identification. It explores missing details of LPV system theory that have hindered the formulation of a well established identification framework.

A Converse Lyapunov Theorem for Linear Parameter-Varying and Linear Switching Systems
SIAM Journal on Control and Optimization, 2005The author is interested in time varying linear systems with the structure \[ \dot x=A\bigl(\theta(t)\bigr),\quad x\in\mathbb{K}^n \] where \(\mathbb{K}=\mathbb{R}\) or \(\mathbb{C}\). Here, \(\theta(t)\) is an admissible parameter variation, meaning that \(\theta(t)\) is piecewise absolutely continuous with dwell time (i.e., length of the time ...

Nonparametric methods for the identification of linear parameter varying systems
2008 IEEE International Conference on Computer-Aided Control Systems, 2008In this paper, we consider the identification of linear parameter varying (LPV) systems. By taking a nonparametric approach, we do not impose a priori parameterizations on the model structure, nor is it assumed that a natural parameterization is suggested from an analytical understanding of the underlying process. In this case, it is shown that the LPV

Geometric Theory and Control of Linear Parameter Varying Systems
2007 4th International Symposium on Applied Computational Intelligence and Informatics, 2007Linear Parameter Varying (LPV) systems appear in a form of LTI state space representations where the elements of the A(rho), B(rho), C(rho) matrices depend on an unknown but at any time instant measurable vector parameter rho isin V. This paper describes a geometric view of LPV systems. Geometric concepts and tools of invariant subspaces and algorithms

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 ...

Set-valued methods for linear parameter varying systems
Automatica, 1999The following linear parameter varying (LPV) system \[ x(k+1) \in F(\theta (k)) \left( x(k) u(k)\right) +B_1d(k), x(0)=x_0, \] \[ \theta (k+1)\in Q(\theta (k)), \theta (0)=\theta _0, \quad z(k)=\left( Cx(k) Du(k) \right) \] is considered where \(u\) is a control, \(d\) is a disturbance, \(z\) is a regulated output and \(F\) and \(Q\) are set-valued ...

Distributed control for distributed linear parameter varying systems
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001Considers stability analysis and performance control for distributed systems with time and spatial varying parameters. The distributed linear parameter-varying (LPV) system depends on the parameters in linear fractional transformation form. The parameters are assumed measurable in real-time for controller use.

Parameter Dependent Lyapunov functions for stability of Linear Parameter Varying systems
2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010the problem in this paper consists in developing a new robust stability condition for Linear Parameter Varying (LPV) continuous systems, under polytopic uncertainty structure. The main skill is the use of Parameter Dependent Lyapunov functions with (PDLFs) particular forms.
