We propose the method of investigation of highly dissipative systems, which are based on the approximation of the attractor by some manifold. The projection dynamic equations for the general form of such manifold of the dissipative dynamic system are obtained. Variational principles for the projection dynamics are considered. On the basis of the projection dynamic equations we investigate the influence of the random forces on the behaviour of the system.
