Claim Text:
1. An orbit attitude control device, comprising: a plurality of nozzles configured to inject combustion gas supplied from a combustion chamber, in which opening degrees are configured to be controlled in accordance with opening degree command values; and a control section configured to calculate nozzle opening degree correction values that are correction values for opening degree command values so that a deviation between a detection value of a pressure of the combustion chamber and a command value of the pressure becomes smaller to correct the opening degree command values by the nozzle opening degree correction values, wherein first group nozzles which belong to a first group of the plurality of nozzles are configured to inject combustion gas in opposite directions along a first axis, a second group nozzles which belong to a second group of the plurality of nozzles are configured to inject combustion gas in opposite directions along a second axis, wherein the control section is configured to: calculate a total correction value that is a correction value for a total of the opening degree command values for the plurality of nozzles so that the deviation between the detection value of the pressure and the command value of the pressure becomes smaller; calculate a total first group opening degree value T distribute the total correction value into a first group opening degree correction value with a ratio of T calculate the nozzle opening degree correction values for the first group nozzles so that a total value becomes the first group opening degree correction value; and calculate the nozzle opening degree correction values for the second group nozzles so that a total value becomes the second group opening degree correction value.
