In the controller configured to perform differential D control calculation and output an operation control signal to the process, a pre-initial operation detection means for detecting a state in which a predetermined operation button has never been pressed after shipment from the factory; When a signal indicating that a predetermined operation button has not been pressed since shipment from the factory is received from the initial operation pre-detection means and the initial operation is started, the process characteristics are identified, and P is activated based on the identification results.
A simple controller comprising: process identification means for determining an ID calculation constant and automatically setting the determined PID calculation constant in a PID control calculation section.
