Stability of parametrically excited differential equations

Dickerson, John Randall (1967)
Sufficient stability criteria for classes of parametrically excited differential equations are developed and applied to example problems of a dynamical nature. Stability requirements are presented in terms of 1) the modulus of the amplitude of the parametric terms, 2) the modulus of the integral of the parametric terms and 3) the modulus of the derivative of the parametric terms. The methods employed to show stability are Liapunov's Direct Method and the Gronwall Lemma. Th...
