On Synthesis of Practically Valid Gain-Scheduled Controllers
2003 (English)Report (Other academic)
Abstract Sucient conditions for the existence of a gain scheduled controller for LPV systems is presented. It is shown that it is always possible to, and a controller that depends on the parameters but which is independent of the rate of parameter variation. The conditions are three LMIs, which are similar to the conditions used for standard H1 synthesis problems. In the general case, the controller needs to have twice as many states as the original system. If a lower-order controllers is searched for, a rate- independent controller still resists a convex formulation.
