Abstract : The results of certain investigations of stability and the degree of stability of nonlinear control systems with one or two regulators are reported. The problems considered concern what is called absolute stability, i.e., stability under unbounded perturbations, with regulators of arbitrary nonlinear characteristics defined precisely only to the extent of their belonging to a certain class of functions. A general study, first begun by A.I. Lur'ye, is developed, generalized, and extended to cover a whole series of broader and more complicated classes of control systems, and various methods are set forth for solving problems in the absolute stability of control systems.
