Abstract

We derive sufficient conditions for the existence of invariant sets for Lure nonlinear systems where the nonlinearity is not matched with the control input. The sector bounded non-linearity is represented as a time-varying parameterised linear function with bounded parameter variations, and the invariant sets are computed by embedding the nonlinear system into a convex polytopic LPV system. We show that the 'matching' condition for the nonlinearity can be relaxed for the case when the matrices associated with the nonlinearity satisfy a special relation. An example of a flexible manipulator is provided to illustrate the results.
