The Jacobi theory of integration of dynamical equations that admit first integrals and invariant sets is developed. Stability of solutions of difference equations is investigated by means of Lyapunov functions as quadratic forms. The method of control of unstable mechanical systems with the deficit of control influences is offered. The bifurcation sets for dynamical model of an automobile are studied.
