Abstract
A steering control device synchronizes the driving operations of swash plate control servomechanisms. In roll control, the control amount adjustment circuit separates and converts the roll control signal into a roll servo drive control amount and a collective pitch servo drive control amount. The offset correction circuit offset-corrects the converted control amounts and outputs a servo control signal converted into the roll servo control amount and a servo control signal converted into the collective pitch servo control amount. The adder receives the roll servo control signal and the collective pitch servo control signal and adds them with a pitch control signal and a collective pitch control signal. Thereafter, the synchronous circuit synchronizes the added signals. The roll servo control output, the pitch servo output, and the collective pitch output are respectively output to the servo mechanisms with the same timing.
