Stability Results of Popov-Type for Infinite-Dimensional Systems with Applications to Integral Control (2008)

R. F. Curtain, H. Logemann, Claverton Down, O. Staffans

We derive absolute stability results of Popov-type for in nite-dimensional systems in an input-output setting. Our results apply to feedback systems where the linear part is the series...

Absolute Stability Results in Infinite Dimensions (2007)

R. F. Curtain, H. Logemann, Claverton Down, O. Staffans

We derive absolute stability results of Popov and circle-criterion type for in nite-dimensional systems in an input-output setting. Our results apply to feedback systems where the linear part is the...
