PURPOSE:To eliminate a dynamic error by a method wherein a difference between a logical commanding value and the rotating angle of a servomotor is detected by a synchro differential generator and is added to the logical commanding value to give an actual commanding value. CONSTITUTION:The first synchro differential generator 2 is directly connected to a detector 1 to detect the rolling angle of a ship and generates a synchro signal. Here, the synchro signal is a value corrected by a correcting value from the second synchro differential generator 7. A synchro receiver 3 receives the synchro signal from the generator 2 and outputs the differential signal from the actual rotating angle of a servomotor generator 5. Further, a servo amplifier 4 amplifies this differential signal and drives the servomotor generator 5 to correct the rolling angle of a load 6. According to this method, the error of the servomotor generator 5 may be corrected to zero. |
