Analysis of parametric sensitivity and structural optimization of modal control systems with state controllers

The problem of synthesis of parametrically robust modal control systems with inertialess and dynamic state controllers is considered. The dependence of the domain of parametric robustness of the system with the state controller on the mutual position of zeros and poles and the structure of the control plant is studied. It is demonstrated that the analysis of norms of coordinate transformation matrices of a plant and the construction of zones of parametric robustness make it possible to choose the most efficient structure of the modal control system.
