We consider a class of second-order nonlinear delay differential equations with periodic coefficients in linear terms.We obtain conditions under which the zero solution is cardio and Eport Signal Wire asymptotically stable.Estimates for attraction sets and decay rates of solutions Vacuum Cloth Bag at infinity are established.
This class of equations includes the equation of vibrations of the inverted pendulum, the suspension point of which performs arbitrary periodic oscillations along the vertical line.
