Appropriate realisation of MIMO gain-scheduled controllers

Appropriate Realisation of MIMO Gain-Scheduled Controllers D.J.Leith

The dynamic characteristics of a controller designed by the gain-scheduling approach can be strongly dependent on the realisation adopted; that is, the manner in which the local linear controller designs are combined to obtain a nonlocal controller. The purpose of the present paper is to investigate the choice of appropriate realisations for general MIMO gain-scheduled controllers. An extended ...

A velocity algorithm for the implementation of gain-scheduled controllers

A new method is proposed to implement gain-scheduled controllers for nonlinear plants. Given a family of linear feedback controllers designed for linearizations of a nonlinear plant about constant operating points, a nonlinear gain-scheduled controller is derived that preserves the input-output properties of the linear closed loop systems locally, about each equilibrium point. The key procedure...

Robust Control Design of Gain-scheduled Controllers for Nonlinear Processes

Design of Robust Gain-scheduled Mpc Controllers for Nonlinear Processes

A methodology is proposed for the analysis and design of a robust gainscheduled Model predictive Controllers (MPC) for nonlinear chemical processes. The stability and performance tests can be formulated as a finite set of linear matrix inequalities (LMI). A simulation study of a 2x2 system indicates that this approach can provide useful robust controllers, which guarantee closed-loop robust sta...

A Convex Characterization of Gain-scheduled H 1 Controllers

An important class of linear time-varying systems consists of plants where the state-space matrices are xed functions of some time-varying physical parameters. Small Gain techniques can be applied to such systems to derive robust time-invariant controllers. Yet, this approach is often overly conservative when the parameters undergo large variations during system operation. In general, much high...
