Abstract
PURPOSE:To perform an excellently responsive gyroscopic moment compensation by compensating the rotating component output from a main controller through the valve obtained by multiplying the output of the rotational speed detector of a rotator by the differential output of the rotational component of an estimated displacement of the center of gravity. CONSTITUTION:A displacement estimate device 30 is connected to a detecting part, the estimated displacement of the center of gravity obtained here is supplied to main controllers 40, 50 and a gyroscopic moment compensator 60, and the estimated bearing displacement is supplied to an unbalanced rigidity compensator 80. The main controller 40, 50 obtain the command value of a generalized force which acts to the center of gravity from the estimated displacement of the center of gravity and the center of gravity displacement command value. Following this, the gyroscopic moment compensator 60 obtains the product of the angular velocity of a rotator supplied from a rotational speed detector 6 and the moment of inertia about (x) axis, and the compensation value of the gyroscopic moment is calculated by multiplying this product by the output of differential elements.
