をすることを特徴とする変化率検出方法。 In a control method that uses rate of change for process control, a data buffer memory is provided that can store enough rate of change data to be averaged, and at each sampling time, calculations are performed using the current data and the previous sampling value. A method for detecting a rate of change, comprising sequentially shifting and storing the rate of change data obtained in the data buffer memory, and then extracting all the stored data and calculating an average value.
