Absolute stability results for well-posed infinite-dimensional systems with applications to low-gain integral control
We derive absolute stability results for well-posed infinite-dimensional systems which, in a sense, extend the well-known circle criterion to the case that the underlying linear system is the series interconnection of an exponentially stable well-posed infinite-dimensional system and an integrator and the nonlinearity satisfies a sector condition of the form () ≤ 0 for some constant . These results are used to prove convergence and stability properties of low-gain integral feedback control applied...
