Methods for Assessing the Robustness Properties of a Linear Multivariable Feedback Design

摘要

On completing the design of a multivariable feedback system it is always desirable to be able to predict that under certain changes the system will remain stable. In these notes some methods are described for determining the robustness properties of a multivariable feedback system under (1) simultaneous variation of sensor (or actuator) gains; (2) simultaneous nonlinear perturbations of loop gains; and (3) plant parameter uncertainty.
