Controller synthesis for linear parameter varying (lpv) systems has received a lot of attention from the control community. This is mainly motivated by the wide range of non-linear dynamical systems that can be approximated by lpv-systems. In this paper a novel method is presented that, by only using local state space models as data, tries to solve the problem of finding a linear parameter vary...

A new method for the design of fixed-structure dynamic output-feedback Linear Parameter Varying (LPV) controllers for discrete-time LPV systems with bounded scheduling parameter variations is presented. Sufficient conditions for the stability, H2 and induced l2-norm performance of a given LPV system are given through a set of Linear Matrix Inequalities (LMIs) and exploited for design. Extension...

In this paper, we develop a reliable Linear Parameter-Varying (LPV) model of the pitch channel dynamics fin-stabilized projectile. Among available LPV design approaches, State Transformation is analyzed, being particularly suitable for class systems defined as output nonlinear, and compatible with projectile formulation. The provides quasi-LPV representation, which corresponds to an exact trans...

Methods Following written consent, male and female volunteers were administered LPV/r 400/100 (2 LPV/r Meltrex 200/50 tablets; regimen 1), 200/150 (1 Meltrex tablet, 1 100mg ritonavir capsule; regimen 2), and 200/50 (1 Meltrex tablet; regimen 3) mg twice daily (BID) for 7 days sequentially. Each 7-day phase was separated by a 7-day wash-out period and LPV/r steady-state PK was assessed over 12 ...

This paper presents case studies of robust algorithm of multi-parametric model predictive control (mpMPC). For discrete-time linear parameter-varying (LPV) systems, the robust algorithm is investigated based on the solution of the mpMPC problem for discrete-time linear time-invariant (LTI) systems. The algorithm provides a controller design method, adaptable to parameter changes of a LPV system...

We address the problem of H 1 gain-scheduling of a magnetic bearing/rotor system with the speed of the rotor being the scheduling parameter. The rotor exhibits signiicant gyroscopics. As a result, the plant dynamics change with the rotor speed. Recent results in the theory of LPV systems can be used to design robust, gain-scheduled controllers for such a system. As opposed to traditional gain-s...

Linear Parameter-Varying (LPV) systems with piecewise differentiable parameters is a class of LPV systems for which no proper analysis conditions have been obtained so far. To fill this gap, we propose an approach based on the theory of hybrid systems. The underlying idea is to reformulate the considered LPV system as an equivalent hybrid system that will incorporate, through a suitable state a...

In this paper, a leak detection, isolation and estimation methodology in pressurized water pipe networks is proposed. The methodology is based on computing residuals which are obtained comparing measured pressures (heads) in selected points of the network with their estimated values by means of a Linear Parameter Varying (LPV) model and zonotopes. The structure of the LPV model is obtained from...

This paper examines a switching LPV control approach to determine if it is practical to use for flight control designs within a wide angle of attack region. The approach is based on multiple parameter-dependent Lyapunov functions. The full parameter space is partitioned into overlapping subspaces and a family of LPV controllers are designed, each suitable for a specific parameter subspace. The ...

Nonlinear plants can often be modelled as linear parameter varying (LPV) plants for which a number of techniques exist for control synthesis. However, there are some systems for which such a technique presents difficulties. In this paper, we consider one such system for which we propose a pole placement method using state feedback in order to cancel parameters variation of LPV plants. Hence, an...
