Abstract

PURPOSE:To stabilize the early control accuracy of off-centering of roll by defining the wave shape of operational signal given off by making allowance for phase lag at the onset of control at a point past zero point in the first place after control command is given. CONSTITUTION:When a control input command is given from the operational table 24 to the digital computer 17, the computer 17 memorizes the changed wave corresponding to the rotation of the roll 1 and then the amount of roll off-center compensation which advanced phase in advance by making an allowance for the lag of control system is sent to the D/A convertor 22. The output signal 42 of the D/A convertor 22 is compared with the signal from the comparative deviation value generator 40 by the comparator 29, and when it is judged as zero value for the first time after the control input command of the signal 42 is given, flip-flop is set up. From this time, the switch 27 becomes active to start a control on the off-centering of roll.
