Optimality and Stability Properties of PD-controllers for a Class of Nonlinear Siso Network Systems
Author:
Abstract: In this paper the stability and optimality properties of a class of PD controlled nonlinear SISO network systems is analyzed. The considered system class embraces network systems with input-output relative degree two and asymptotically stable zero dynamics. A set of semi-global stability conditions is derived which can be interpreted as tuning guidelines. The PD-controller optimality conditions are derived on the basis of a passivity property with respect to a suitable (control) output using inverse optimality.
