PURPOSE:To constitute a stable servo system corresponding always to a load, by judging its pattern from the current waveform of a motor and by automatically adjusting a gain constant, etc., according to each pattern. CONSTITUTION:A pattern recognition section 7 extracts its characteristic from a current waveform flowing to a motor 5 and at the same time recognizes the change of the current waveform. A memory 8 stores an appropriate gain constant according to the change of various kinds of current waveform. The variation value of the current waveform is thereby acknowledged with the pattern recognition section 7 while the motor 5 is in operation and by selecting the predetermined gain constant from the memory 8, the moment of inertia for the load and motor constant are estimated, so that the stable servo system corresponding always to the load is constituted. |
