Filed: 1973-11-27
Abstract: 1471156 Automatic control GEC-ELLIOTT AUTOMATION Ltd 27 Nov 1974 [27 Nov 1973] 54879/73 Heading G3N In a system for controlling the attitude or course of an aquatic vessel, ship, drilling platform or hovercraft, by controlling the thrust and direction of independent bow and stern thrusters, means are provided for reproportioning the relative outputs of the thrusters in respect of the thrust exerted along an axis joining the two thrusters to maintain, or to bring, the output of one of the thrusters below a predetermined level, without altering the net thrust along said axis or at right angles to said axis, or producing a turning movement of the vessel. In Fig. 5b, bow and stern thrusters, or groups of thrusters, are automatically positioned and controlled to produce the respective thrust vectors XB, YB and Xs Ys equivalent to net thrusts X and Y and turning moment N shown in Fig. 5a. The values of X, Y and N are calculated by unspecified means from measurements of external forces and the required values of Y B , Y S  and X B , X S  are derived therefrom as shown in Fig. 2. The symbol P represents the proportion of the X direction thrust to be provided by the bow thruster and this is initially 0.5 but is re-adjusted periodically at 2 in equal increments produced by the "digital filter" 4 according to the equation shown therein, wherein α is an exponential constant and U1 has the value +0À5, -0À5 or 0 depending upon whether the power supplied to either of the thrusters exceeds a limit or they are equal, as determined by a logic circuit 5 (also Fig. 3, not shown). U2 has the value 0À3 when either of the thrusters is pointing in an undesirable direction, e.g. the wake of one becomes the intake to the other; a list of these directions is stored in a memory Fig. 4, (not shown). Re-adjustment of thrust in the X direction is accompanied by a change in the direction of the thrusters so as to keep Y and T constant. There may be a pair of thrusters on the ship's centre line at the bow and a pair athwartship at the stern, all electrically powered from a diesel driven alternator.
