Abstract :
The stability of a system described by the n th-order differential equation y^(n) + a_{n-1}Y^(n-1) + ... + a_{1}\\dot{Y} + a_{0}y = 0 where a_{i} = a_{i}(t, y, \\dot{y}, ... , y^(n-1)) , i = 0,1,2, ... , n-1 is considered. It is shown that if the instantaneous roots of the characteristic equation of the system are always contained in a circle on the complex plane with center ( - z, 0 ), z > 0 and radius ω such that frac{z}{\\Omega } > {{1, n = 1}{\\sqrt {2n(n-1)}, n \\geq 2} then the system is uniformly asymptotically stable in the sense of Liapunov.
