Abstract

1,257,779. Automatic optimizing control. ROLLS-ROYCE Ltd. Dec.19, 1968 [Dec.21, 1967; Dec.29, 1967], Nos.58002/67 and 59028/67. Heading G3R. A digital computer perturbates a manufacturing or power plant in dependence on a pseudo-random binary sequence having two types of digit, one of which produces ramp perturbation signals of opposite slope alternately and the other of which maintains the perturbation signal constant, signals being developed in accordance with the effect of the perturbation on the plant output to drive the latter to a maximum or minimum. In Fig.1, a digital computer 28 derives ramp pulses from random binary sequences and applies them at B 1 and B 2 to oscillate a fuel valve 22 and a nozzle actuator 24 of a gas turbine 10. Signals corresponding to the resulting changes in engine thrust, produced at 26, are supplied to computer 28 which utilizes the binary sequences to separate the thrust variation signals into components corresponding to fuel and nozzle variations. The rates of change (slopes) of these components relative to the changes producing them are divided by their differentials (curvatures) to develop signals Z 1 , Z 2 which are applied to adjust valve 22 and actuator 24 in the senses necessary to increase thrust. These adjustments are repeated at intervals to attain and maintain optimum thrust.
