計。 The controller consists of an input section that inputs the measured quantity from the process, a calculation section that performs a predetermined control calculation operation according to the control parameters in accordance with the input signal, and an output section that outputs the calculation results.The controller calculates the rate of change of the control parameter. A control parameter change detection section is provided, which consists of a control parameter change calculation section, an absolute value calculation section that calculates the absolute value of the control parameter change, and a comparison section that outputs a reset signal to the integral element when the absolute value of the control parameter change changes. A controller characterized in that the operation output is balanced and bumpless even if control parameters are changed at the time of occurrence.
