PROBLEM TO BE SOLVED: To make a current supplied to a magnetic torquer constant and also lessen a magnetic torquer control device and facilitate the loading property of an artificial satellite by outputting a control current detected by a control current detector to the magnetic torquer. SOLUTION: In the pulse width modulation circuits 12a-12c of a magnetic torquer control device 7, the pulse width of the control currents 8a-8c detected by control current detectors 16a-16c is moved by a control feedback signal 16. While, a primary electric source 4 is turned on and off by on/off circuits 11a-11c according to the indication of the control order signal 6 issued by a posture control device 5. The output of the on/off circuits 11a-11c is outputted to the magnetic torcas 9a-9c as the control currents 8a-8c controlled to a constant by the pulse width signals 13a-13c of the output of the pulse width modulation circuits 12a-12c in the switching circuits 14a-14c. Thereby, a stable control is carried out for the temperature change of the magnetic torcas 9a-9c and also a magnetic torquer control device 7 can be minified.
