Sensitivity of Closed Loop System Eigenvalues to Structured Perturbations in System Parameters

The dynamic behavior of any control system is totally dictated by the eigenvalues of the closed loop system matrix (A-BF). Any small changes in system parameters lead to real problems of unknown results. In this paper a methodology has been introduced to predict and calculate the sensitivities of each closed loop eigenvalue due to any perturbation in the elements of the system matrix A.
