Steady-state solutions of nonlinear model of inverted pendulum. (English) Zbl 0993.60051
The authors consider the nonlinear mathematical model of inverted pendulum \(\ddot{x}(t)-(a+\sigma\dot\xi(t))x(t)=u(t)\) with the control \(u(t)=\int_0^{\infty}dK(\tau)x(t-\tau)\), the initial conditions \(x(s)=\varphi(s)\), \(\dot{x}(s)=\dot\varphi(s)\) and with the stochastic perturbations \(\dot\xi(t)\) of the white noise type. The nonclassical method of stabilization of this pendulum is exploited. Nonzero steady-state solutions of this system are studied. Conditions under which equilibrium points of the model are stable, unstable or one-sided stable are obtained. Theoretical results are illustrated by numerical examples.
