Abstract

PURPOSE:To realize the dynamic change of a servo constant by using a programmable gain amplifier to an analog servo device and using a D/A converter to form said programmable amplifier. CONSTITUTION:The target value undergone the D/A conversion 3 is supplied to one of both inputs of an analog subtractor 4. While the observed value received from a controlled system 5 is supplied to the other input of the subtractor 4. The deviation between the target value and the observed value is outputted to the programmable gain amplifiers 6 and 7 consisting of the D/A converters respectively. The output of the amplifier 6 is supplied to one of both inputs of an analog adder 8; while the output of the amplifier 7 is differentiated by a differentiator 9 and supplied to the other input of the adder 8. Then the added value of both outputs of amplifiers 6 and 7 is applied to the controlled system 5 as the controlled variable. With use of such amplifiers 6 and 7, the gain and then a servo constant can be changed without substantially applying the load to software since the gain is set just by writing the digital value to the D/A converter. Thus the servo constant can be dynamically changed.
