Linear, parameter-varying control of a supercavitating vehicle

Control Engineering Practice, 2009
A systematic approach to parameter-dependent control synthesis of a high-speed supercavitation vehicle (HSSV) is presented. The aim of the control design is to provide robust reference tracking across a large flight envelope, while directly accounting for the interaction of liquid and gas phases with the vehicle.

Linear parameter-varying descriptions of nonlinear systems

Proceedings of the 2004 American Control Conference, 2004
Recent 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., 2004
This 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.

On Stability of Linear Varying-Parameter Systems

Journal of Applied Physics, 1951
A linear varying-parameter system is defined to be stable if and only if every bounded input produces a bounded output. It is shown that a necessary and sufficient condition for stability is that the impulsive response of the system W(t, τ) should be integrable (considered as a function τ) for all t.

Cooperative control of linear parameter-varying systems

2012 American Control Conference (ACC), 2012
The 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.

Identification of linear parameter-varying engine models

2013 American Control Conference, 2013
The real-time identification and monitoring of automotive engines has posed many challenging problems. The difficulties are mainly due to the nonlinearity of the engine dynamics due to changes in the engine operating conditions. Various recent studies have demonstrated that many of the powertrain subsystems are well approximated as linear parameter ...

Linear Parameter Varying control of a quadrotor

2011 6th International Conference on Industrial and Information Systems, 2011
This paper describes a Linear Parameter Varying (LPV) controller design for a quadrotor vehicle. The controller synthesis requires the LPV plant model which is obtained by linearisation of the modelling equations, to be in an affine form. However, the LPV representation of the quadrotor dynamic is not affine; hence it has been transformed into to a ...

Initial Conditions in Linear Varying-Parameter Systems

Journal of Applied Physics, 1951
The problem considered in this paper is that of determining the response of an initially excited linear varying-parameter system to a given input. Mathematically, this problem reduces to solving a linear differential equation (with time-dependent coefficients) subject to prescribed initial conditions.
