We propose a general approach to analysis and control of dynamical behavior of an automata network. The properties of connectness, reachability and optimality under phase constraints and/or persistently acting perturbations are considered. We reduce automata model complexity by means of model transformations in a class of logical functions. These functions play an important part in our theory and act as Lyapunov functions in stability theory or homomorphisms in automata theory. In terms of these logical functions criteria of existence of above mentioned properties are formulated. Constructive algorithms of generating the logical functions satisfying the criteria as well as examples of their application are described.

THIS PAPER PRESENTS the results of a ship braking and reversing dynamics study for a COGAG, single screw, ship with a fixed pitch propeller, a reversing reduction gear, and a water brake for dynamic braking of the propeller. A digital computer simulation was used to calculate the major ship and propulsion plant parameters for various propulsion maneuvers including coast down, braking, and reversing. A computer technique for solving the ship propulsion dynamics equations is described, the equations for clutching and braking are derived, and the results of braking and reversing maneuvers for speeds greater than 30 knots are shown in detail for a hypothetical study ship.
