A Singular Value Decomposition Based Closed Loop Stability Preserving Controller Reduction Method

• In this paper a controller reduction method whichpreserves closed loop stability is described. A Lyapunov inequalitybased sufficient condition is proposed in the search ofthe reduced controller. The reduced controller leads to a stableclosed loop system with guaranteed approximation quality. Furthermore,the proposed problem can be formulated as a matrixapproximation problem which can be solved efficiently usingsingular value decomposition. Numerical application examplesare shown in the end to evaluate the generality of the proposedreduction method.
