フィードバック制御系に対するロバスト安定性の図式的判別法

This paper is concerned with a test for robust stability. In order to overcome the conservativeness of usual stability test based on the small gain theorem, a new graphical test is introduced for robust stability of scalar systems, which takes account of both gain and phase information. The method is then extended to a class of multivariable systems.
