摘要： Automatic control device 1 controls servo motor 50. Automatic control device 1 is provided with control section 10 that calculates operation amount 102 of servo motor 50 based on the difference between current value 105 and target value 101 of a control amount of servo motor 50. Automatic control device 1 is also provided with first filter 20 that outputs first output value 103 after using a first filter coefficient or a second filter coefficient to perform filtering of operation amount 102 calculated by control section 10. Automatic control device 1 is also provided with second filter 30, arranged in parallel with first filter 20, that outputs second output value 104 after using a third filter coefficient to perform filtering of operation amount 102 calculated by control section 10. Automatic control device 1 is also provided with switching section 40 that switches between first output value 103 of first filter 20 and second output value 104 of second filter 40 and sends one of the output values to servo motor 50.
