Abstract:
This article presents a procedure for control synthesis of linear timevarying (LTV) structured systems. A well-known problem, the decoupling by state feedback is solved for LTV models. Moreover, for the problem of decoupling with stability a solution is provided using a graphical procedure based on the (A,B)-invariance. All these concept are extended to nonlinear models, by passing trough the tangential system which can be considered as an LTV model. An algorithm for input-output decoupling and linearization of nonlinear models, using the LTV structured systems is introduced. Copyright © 2007 IFAC.
