<P>PROBLEM TO BE SOLVED: To provide a mode switching device of a PID control unit for, when switching an operation mode of the PID control unit to a manual mode and an automatic mode, stably switching the mode by removing any impact generated due to the switching of the mode. <P>SOLUTION: The mode switching device of a PID control unit comprises: a PID arithmetic part for performing the PID arithmetic operation of an automatic mode and a manual mode according to a manual mode switching signal and an automatic mode switching signal, and for generating a driving signal; a manual mode buffering part for, when the manual mode switching signal is generated, processing the driving signal generated by the PID arithmetic part, and for outputting the driving signal to a load driving machine; and a speed difference integration signal calculation part for, when an automatic mode switching signal is generated, analyzing the driving signal generated by the PID arithmetic part, and for outputting the driving signal to the PID arithmetic part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
